Late twentieth-century housing, formed by economic and internally generated functional problems rather than by limitations imposed by traditional street pattern and block size, is fundamentally anti-urban. Modern American housing of the post-World War II era, like any complex social phenomenon, was influenced by multiple forces. Among the most salient are single proprietary control of large parcels of urban land and pre-World War II stylistic trends / social ideals, both of which were reinforced by revisions to zoning regulations. The traditional relationship of the individual dwelling to the block and the street (as well as the individual to the community, as represented by a parallel, formal urban organization) is altered as a result of a changed urban housing configuration. Although the urban characteristics of traditional eighteenth- and nineteenth-century housing blocks remain viable, the dwellings of which they were composed were products of an economic and social structure whose housing requirements are no longer appropriate in contemporary culture. Modem housing, not limited by normative street and block configuration fulfills some of the economic and programmatic requirements of contemporary society, but because it is inherently anti-urban its presence is ultimately destructive of civic life. Analysis of traditional residential urban blocks in terms of quantifiable urban characteristics provides a tool with which to measure and generate programatically modern housing determined by traditional urban constraints.

Testo completoThis thesis develops a 3-degree of freedom submarine drydock blocking system computer aided design package. Differential equations of motion are developed to take into account high blocking systems, wale shores, and side block cap angles. The computer program is verified by a case study involving the earthquake sliding failure of the USS Leahy (CG-16). A parametric study is conducted to determine the effects of wale shores, isolators, and block stiffness and geometry variations on system survivability. The effects of using earthquake acceleration time histories with differing frequency spectrums on system survivability is studied. None of eleven submarine drydock blocking systems studied survive to dry dock failure (0.26 g's) or even meet the Navy's current 0.2 g survival requirement. This shows that current Navy submarine drydock blocking systems are inadequate to survive expected earthquakes. Two design solutions are found that meet the dry dock failure requirements. The low stiffness solution uses dynamic isolators and rubber caps, and the high stiffness solution uses wale shores and rubber caps. The wale shore solution virtually prevents the submarine from moving horizontally relative to the dock floor. The isolator solution allows relatively large horizontal displacements to occur. Using the wale shore solution, the submarine experiences forces which are an order of magnitude higher than these seen by the isolator solution. Both design solutions can be constructed; however, there are cost and production interference concerns. Theses. (edc)

The tendency of block copolymers (BCP's) to microphase separate at the molecular level, producing a wide array of ordered nanostructures, is of particular interest from an engineering standpoint due to the unique mechanical, optical or electrical properties that ensue. Upon considering the potential applications of these materials, however, one limitation arises from the lack of control over bulk thermodynamics and the appearance of order/disorder (solid-like/liquid-like) transitions in these materials. To address this problem, this thesis aims to, firstly, develop a more quantifiable understanding of the molecular factors governing BCP phase behavior, and, secondly, use that knowledge to molecularly engineer new BCP's with enhanced processibility. While most BCP's microphase separate upon cooling through an upper disorder-to-order transition (UDOT), polystyrene-block-poly n-butyl methacrylate, PS-b-PBMA, undergoes ordering upon heating through a lower disorder-to-order transition (LDOT). Preliminary studies on this material revealed a unique pressure sensitivity of this ordering transition. By applying pressure, this material could be forced into the segmentally mixed liquid state, implying "baroplasticity", a highly attractive property from a processing standpoint. To better understand the molecular origin of this behavior, the bulk thermodynamics of a family of BCPs formed from styrene and a homologous series of n-alkyl methacrylates (PS-b-PnAMA, n ranging from 1 to 12) was investigated, both as a function of pressure and temperature. The results of this study reveal an unexpected, though systematic, dependence of the phase behavior of these BCP's on monomer architecture. In short, over a certain range of alkyl side chain length, PS-b-PnAMA block copolymers are marginally compatible and exhibit unexpectedly large pressure coefficients for the ordering transition, ranging from 60 to 150°C/kbar. In an attempt to identify molecular parameters responsible for these thermodynamic trends, as well as those displayed by other systems reported in the literature, combined group contribution/lattice fluid model calculations of the cohesive properties of the corresponding homopolymers are performed. Based on this analysis, the homopolymer mass density is proposed as a macroscopic parameter that appears to govern phase behavior in weakly interacting block copolymers or polymer blends. Using this new criterion, a simple tool for the molecular design of phase behavior into weakly interacting BCP's is identified, which is successfully used to engineer "baroplastic" behavior into several new systems of commercial relevance, including elastomers and adhesives based on styrene and low Tg acrylates. In light of the improved understanding of BCP phase behavior emerging from these studies, a simple phenomenological free energy expression is proposed for compressible polymer mixtures, that can be extended to block copolymers. Its ability to predict qualitative phase diagrams for the systems investigated in this thesis as well as many other polymer pairs is demonstrated. Using this expression, basic principles regarding polymer thermodynamics are outlined.

Testo completoThe concept of metamaterials appeared in the years 2000 with the achievement of artificial structures enabling nonconventional propagation of electromagnetic waves. The electromagnetic response of metamaterials is based on the presence of optically resonant elements of sub-wavelength size and well-designed morphology and organization.In order to create controlled geometrical structures inherent to metamaterials design, block copolymer self-assembly constitutes an emerging strategy. Indeed, the periodic structures inherent to their segregation behavior can be used as scaffolds to create various regular or ordered nanoparticles arrays. The main objectives of this study is to demonstrate that block copolymer can indeed lead to a high level of control of a variety of designed nanostructures, in an easy and scalable method, and to correlate the structural parameters of the nanoparticles arrays and their optical properties.As a first demonstration, a lamellar-forming (poly(styrene)-block-poly(2-vinylpyridine) was used to create high refractive index surfaces. The selective and customizable metal incorporation within the out-of-plane lamellae produces azimuthally isotropic metallic nanostructures of defined geometries, for which a clear relationship between the gold content and the refractive index was established. Further studies were dedicated to the correlation between the geometrical parameters of the nanoparticles arrays and the optical properties through the macromolecular engineering of a series of cylinder-forming block copolymers having a wide range of molecular weights. Through this strategy, the particle diameter and the inter-particle distance were tuned leading to the production of metasurfaces with various optical characteristics. More complex metasurface designs were also obtained using a layer-by-layer self-assembly strategy, i.e. bimetallic raspberry nanoclusters or layered hybrid (metallic/polymer) structures. In all cases, the nanoparticles arrays were thoroughly analyzed using microscopy and small-angle X-ray scattering techniques in order to better apprehend the optical properties derived from variable-angle spectroscopic ellipsometry analysis

Testo completoBagheri, Mehdi. "Model uncertainty of design tools to analyze block stability". Licentiate thesis, KTH, Civil and Architectural Engineering, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-10580.
Testo completoBlock failure is one of the most common failure modes in tunnels. Design tools have some simplifications and, therefore, they also have some model uncertainties. The purpose of this licentiate thesis is to assess the model uncertainty for different design tools in order to estimate block stability.
Different approaches of kinematic limit equilibrium (KLE) including conventional KLE, limited joint length, limited joint length and stress field consideration and probabilistic KLE were compared to that of DFN-DEM. In this approach, the results of the calibrated DFN-DEM with field mapping were considered to be of true value. The results show that the conventional KLE is overdesign due to it’s over simplification. By considering fracture length and stress field, the volume of predicted unstable blocks is reduced. The probabilistic approach of KLE by considering finite joint length and stress field predicts the volume of unstable blocks to be lower than DFN-DEM approach. Therefore there is a great model uncertainty of our standard design tools for block stability analysis.
The assumption made in this study is that the results from DEM were considered to have a true value; the results from analytical solution based on joint relaxation process were compared to those of DEM in a different condition of depth, K0, apical and friction angle, Kn and Ks value, and ratio of Kn/Ks. The comparison shows that for shallow depth with K0 less than 1, analytical solution leads to an overestimation of block stability. The analytical solution predicts that the block is stable, while the analyses from numerical solution show the block is unstable. The analyses show that by increasing K0, accuracy of analytical solution also increases. Moreover, for the cases with close value of friction angle to semi-apical angle, the use of analytical solution is not recommended. As the ratio of Kn/Ks increases, the accuracy of analytical solution decreases. Increasing the angle ratio (ratio between semi-apical angle to friction angle) is one source of increasing uncertainty in the model. The analytical solution is very uncertain in cases with a low value of K0, and a high value of stiffness ratio and angle ratio. On the other hand, the analytical solution is more certain in conditions with a high value of K0 and a low value of stiffness ratio and angle ratio. According to current information (K0, angle ratio, stiffness ratio), one can determine the value of model uncertainty by using the diagrams presented in Chapter 6 of the thesis. The analyses show that by having more information about the key parameters, the model uncertainty could be identified more precisely. However, having more information means spending more money, and this increase in cost must be compared to the cost of failure or delay in the project or overdesign.
Blockutfall är en av de vanligaste brottformerna i tunnlar. Dimensioneringsverktyg har förenklingar och därför har de viss modelosäkerhet. Syftet med licentiat avhandlingen är att bedöma modelosäkerhet för olika dimensioneringsverktyg för att uppskatta blockstabilitet.
I Olika metoder av KLE inkluderad konventional KLE, begränsad spricklängd och insitu spänning och sannolikhetsbasserad KLE är jämförda med DFN-DEM. I den här metoden kalibreras DFN-DEM med fältkartläggning som är betraktad som sanna värden. Resultat visar att konventionell KLE ger starkt konservative resultat. Genom att betrakta spricklängden och spänningsfältet, så minskar volymen på uppskattade instabila block. Den sannolikhetsbaserade metoden för KLE genom att betrakta finit spricklängd, och spänningsfältet förutser att volymen av de instabila blocken är mindre än de som bedöms med DFN-DEM metoden. Det finns mycket osäkerhet i vår standard dimensioneringsverktyg att uppskatta block stabilitet.
Antagande som gjorts i den studien är att resultatet från DEM är betraktade som sanna värden och resultaten från analytiska lösningar baserad på sprickavlastning är jämförda med resultatet från DEM. Jämförelse visar att för grunda djup och med K0 mindre än 1, den analytiska lösningen leder till en överestimering av blockstabiliteten. Den analytiska lösningen förutsäger att blocket är stabilt medan analys av den numeriska lösningen visar att blocket är instabilt. Analysen visar attgenom en ökning av K0 så ökar tillförlitligheten av den analytiska lösningen. Det visar sig att även att för fall med friktionsvinkel nära semitoppvinkeln så kan den analytiska lösningen inte rekommenderas. Vidare leder en ökning av förhållandet Kn/Ks till att tillförlitligheten av den analytiska lösningen minskar. En ökning av vinkelförhållandet mellan semitoppvinkeln och friktionsvinkeln är källa till en ökning av osäkerhet i modellen. En analytisk lösning är mer osäker i fall av lågt värde på K0 och högt värde på styvhetsförhållandet och vinkelnförhållandet. Å andra sidan, så är den analytiska lösningen mer säker i fall av högt värde på K0, och lågt värde på vinkel förhållandet och styvhetsförhållandet.
Vid given information (K0, styvhetsvärde och vinkel förhållande) kan man bestämma värdet på modellosäkerheten genom att använda diagrammen i avhandlingen. Analysen visar att vid ökad information om nyckelparametrarna, så kan modelosäkerheten identifieras mer exakt. Hur som helst så betyder mer tillgång till information att mer pengar måste satsas och denna kostnad måste gemföras med kostnader för blockinstabilitet eller överdesign.

Chapter 1: Introduction to Polymer Networks and Bottlebrush Block Copolymers We introduce polymer networks and the contribution of this author's thesis in the context of new polymer gel design and analysis of topological defects. We also introduce block copolymers and the key architectural differences between our branched bottlebrush design for block copolymer and liquid crystal block copolymer materials. Chapter 2: A dual role for 1,2,4,5-tetrazines in polymer networks: combining Diels-Alder reactions and metal coordination to generate functional supramolecular gels In this chapter we report the synthesis, characterization, and application of a new type of supramolecular metallogels using 1,2,4,5-tetrazines-containing polymers. This was the first example in our group of attempting to using metal-organic cages as crosslinking structures for polymer networks. Chapter 3: Loops Versus Branch Functionality in Model Click Hydrogels Here we report our work on quantifying topological defects in tri- and tetrafunctional networks and compare fundamental differences between such systems. We demonstrate the ability to count primary loop defects with a distribution of junction functionality. Chapter 4: Quantifying the Impact of Molecular Defects on Polymer Network Elasticity Based on our work in Chapter 3, we correlate the effect of molecular defects on a macroscopically measurable value: elasticity. We use our experimental techniques to help develop a new theory to accurately predict elasticity in end-linked networks. Chapter 5: Graft-through Synthesis and Assembly of Janus Bottlebrush Polymers from A-branch- B Diblock Macromonomers We synthesize branched macromonomers that contain two different polymers polymers to form bottlebrush block copolymers with a novel architecture. Bulk state and thin film self-assembly studies were performed and open the door to new, more complex bottlebrush block copolymers. Chapter 6: Synthesis of Liquid Crystal-Containing A-branch-B Janus Bottlebrush Block Copolymers We synthesize macromonomers that contains a polymer and a liquid crystal and polymerize the branched macromonomers to form Janus-type bottlebrush block copolymers. The bulk state self-assembly behavior was characterized and the alignment of the bottlebrush polymers under a magnetic field is explored.

Testo completoAlong with new cryptanalysis techniques, the security of block ciphers is always evolving. When designing new block ciphers, we thus need to consider these new techniques during the security analysis. In this thesis, we show how to build some core operations for block ciphers to improve the security against some attacks. We first start by describing a method to find optimal (according to some criterion) even-odd permutations for a Generalized Feistel Network. Using a new characterization and an efficient algorithm, we are able to solve a 10-years old problem. We then give new cryptanalysis techniques to improve the division property, along with a new proven optimal criterion for designing S-boxes. We continue with new observations for the design of an alternative key-schedule for AES. We thus give a new key-schedule, which is both more efficient and more secure against some attacks compared to the original one. Finally, we describe a very efficient generic algorithm to break most proposals in white-box cryptography, as well as a dedicated attack on a previously not analyzed scheme, leading to a key-recovery attack in a few seconds

Theater rigging greatly expands both scenic movement and storage options when putting on a production. Small, black-box theaters are often built without rigging equipment in them. Temporary rigging equipment can greatly add to the flexibility of these spaces. A rigging block was designed which can be installed in small theaters by attaching to the existing lighting structure. The design was developed to solve problems encountered when using currently available temporary rigging solutions. The block was designed to lift a 200 pound scenic load while providing a safety factor of 10:1. A dual-pulley arrangement allows for flexibility in the placement of rigging positions and better utilization of the available space. Top and bottom pulleys allow for lines to be routed above the level of the lighting grid. The independent swiveling of the pulleys allows lines to enter and exit the block at different angles, adding significant freedom to the rigging system. Calculations were done to assess the forces and torques to which the block might be subjected. Potential materials were evaluated based on their ability to withstand these forces. An eye was kept toward using available off-the-shelf parts where possible in order to reduce costs and to allow for the system to be used by small theaters working with limited budgets.

In this thesis, biodegradable block copolyesters were specifically designed and synthesized for their susceptibility to pressure-induced mixing. These baroplastic materials are capable of being processed and molded through the application of pressure at temperatures far below those needed in traditional melt-processing of biodegradable polyesters. Pressure molding at low temperatures reduces the danger of chain degradation during processing that is ubiquitous in biodegradable plastics. The compressible regular solution model (CRS), in combination with group contribution (GC) methods and pressure-volume-temperature (PVT) data, was used to predict the phase behavior and pressure-induced miscibility of several block copolymer systems. Small-angle neutron scattering (SANS) experiments confirmed that amorphous forms of the poly([epsilon]-caprolactone-ran-5 ethylene ketal [epsilon]-caprolactone)-block-poly(lactic acid) (PmCL-b-PLA) system exhibit pressure- induced miscibility, and small angle x-ray scattering (SAXS) revealed that the position of the upper disorder-to-order temperature (UDOT) in those systems is near the values predicted by the CRS model.
(cont.) Differential scanning calorimetry measurements suggest that poly(1,5-dioxepan-2-one)-block-poly(lactic acid) (PDXO-b-PLA), which was calculated as being more miscible than PmCL-b-PLA by the CRS model, resides in a mixed state at ambient pressure and temperature. The CRS predictions were found to be more accurate with component parameters derived directly from GC than from PVT data. Pressure processing of multiple systems at low temperatures was conducted, and the mechanical properties of these biodegradable baroplastics (bbps) were measured. Crystallinity plays a complex role in baroplastic behavior that has not been fully elucidated. The strain-to-break and modulus of the bbps is good, but somewhat reduced relative to solvent-cast or melt-processed samples. The tunability of the properties of bbps, combined with their low-temperature processability, make them promising candidates for biomedical materials and environmentally friendly plastics.

In many situations, observations in factorial design experiments may be dependent. In this article, we provide a explicit method to construct balanced designs for 2n and 2n-1 factorial designs when observations in blocks are correlated with positive correlation. We first characterized the balanced design, and then illustrate the method through balanced 23 full factorial designs and 24-1 half replicated factorial designs , finally we explain why the design made by the method is a balanced design and provide an analytical proof of balanced designs for both 2n full factorial designs and 2n-1 half replicated factorial designs .

The high-density mixture and multiple compound attributes can be commonly found in urban blocks in Taiwan. It is why heterogeneous interstices are formed up by the species patches which are grown, flocked, or mixed from urban blocks. The interstice, which is a universe of mixed-use of multi-elements which are highly compounded but can still be kept the individuals, constantly changes under the impact of surroundings. The mixing and compound way of living contributes to the new social behavior and interpersonal relationship, and results in a new social fusion. For that reason, the old design pattern of specific architecture design needs to be reconsidered facing the multiple, unstable, and mixing environments. This design starts with the concept of Meta-Design to create a forming mechanism for the design of mixing-forms, which will allow us to develop the design spontaneously and free from the specific way of architecture design. For its characteristic of interstices and mixing, I choose the block of Yu-le Street, which is nearby the railway station and Cheng-Kung University in Tainan, to demonstrate the forming mechanism of the design. This forming mechanism is based on the theory of Open-Building; starts from the smallest interior space by analyzing the scale of diverse using-capacity in the aspect of “Unites”, “Void space”, and “Interchange of solid and void”; and individually study the steps of “Unites Analyzing”, “Zone & Sector Analyzing”, “Build Forms Analyzing”, and “Design for Vocabulary of Urban Level” from the level of architecture to the level of urban. So a “planning grid” will be found to satisfy any design for forming and the diversity of interior planning. The compound block design contains the permanent elements and other unstable spaces: re-marking the permanents for a new dialogue with environments; and testing the manipulation of diverse infilling to verify the sufficiency of the forming mechanism. After all, this block design is a demonstration to display the idea and the manipulation of this design methodology. It proposes to bring in more inspiration to the creation of design.

Traditionally, parallel architecture design of block-matching are feasible for only full search method because of its extreme operation regularity. The approach of this dissertation is to propose efficient parallel architectures for well-known fast block-matching algorithms to utilize their advantage of low computation complexity. First, three improvements to the 3-step hierarchical search block-matching algorithm are then presented: a multiple-winner search that enhances the estimation accuracy, a method of subsampling that reduces computation and input data amount, and an overlapping strategy that improves the accuracy of large-area search. Experimental results show that combining these techniques provides high- speed and high-precision motion estimators with reduced on-chip buffers and lowered input bandwidth requirements. Then, to implement the 3-step search algorithm efficiently, parallel VLSI architectures with intelligent data arrangement and memory configuration are designed and verified. Techniques for reducing interconnections and external memory accesses are also presented. Because of their low costs, high speeds, and low memory bandwidth requirements, the proposed 3-PE, 9-PE, and 27-PE architectures provide efficient solutions for real-time motion estimations required for video applications of various data rates , from low bit-rate video to HDTV systems.

BCM is a method of combining block codes and set partition of an expanded signal set to construct bandwidth-efficient codes Multilevel coding technique is a powerful method for constructing BCM codes. However , the difficulty and complexity of trellis of a linear block code will increase exponentially with the block length. We will propose a novel design of block coded modulation which has longer length、higher coding gains and lower complexity.

In this thesis, a block turbo code of 802.16e is proposed. Unlike the conventional decoding algorithm requiring empirically derived parameters, the proposed geometric-like algorithm uses hamming distance to compensate the information. Not only improving the error performance, the proposed algorithm also facilitates hardware implementation. Moreover, a design methodology for parallel architecture is presented to meet various throughputs. The memory accessing hazard in parallel architecture can be overcome by the proposed multi-bank-array algorithm. The proposed algorithm is a partition and scheduling technique without extra memory. By the proposed algorithm and parallel design methodology, the block turbo code encoder and decoder defined in WiMAX(802.16e) is implemented. Note that, a design flow from algorithm level (in C language) to hardware level (in Verilog ) is presented. A systemC model is also built to provide a more efficient verification strategy and allows electronic system level design.

This thesis discusses the design and fabrication of a low noise block for a wireless communication system at 2.4 GHz ISM-BAND. It includes a three-stage low noise amplifier (LNA), a single balanced mixer, and a voltage- controlled-oscillator (VCO). The specifications of the system are as follows: RF is 2.4 GHz, LO is 2.278 GHz, IF is 122 MHz. The HP-EEsof Libra was used to simulate and analyze the designed circuit. Since high frequency circuit has strong parasitic effect, the design and tuning procedure, in general, are complicated. Therefore, how to simply the design process is a main task of this thesis. In order to make the results of the simulation and the real circuit measurements are as close as possible, factors such as discontinuities of microstrip circuit and the parasitic effect of the passive components were considered during the simulation process. We used the HP AT41511 transistor to fabricate LNA. The measured results of the designed LNA were as follows: for one-stage LNA, the noise figure was 2.04 dB. The input return loss, output return loss, gain and 1 dB compression point were at -11.39 dB, -19.17 dB, 9.44 dB, and 9.81 dBm, respectively. For the three-stage LNA, the noise figure was 2.38 dB. The input return loss, output return loss, gain and 1 dB compression point were -12.60 dB, -30.00 dB, 27.80 dB, -4.67 dBm, respectively. As regards the single balanced mixer, we used the equivalent circuit of the HP HSMS-8202 diode to design it. Under RF power was 0 dBm, and LO power was 10 dBm, the measured results of the designed of mixer were as follows: the conversion loss was -7.31 dB, the 1 dB compression point was 8.26 dBm, the noise figure was 9.10 dB, the RF to IF isolation was -35.01 dB, the IF to RF isolation was -41.00 dB, the LO to RF isolation was -35.48 dB, the RF port SWR was 2.52, the LO port SWR was 1.3 and the IF port SWR was 1.13. A NEC NE85633 transistor was used to fabricate the VCO, and it was operated at 2.278 GHz. The frequency tuning range of the VCO was 41.8 MHz under the reverse bias voltage of the varactor diode varied from 0V to 5V. The oscillator phase noise was -87.27 dBc/Hz at 10 KHz away from the center frequency.

This study explores theories on designing two-point interconnection structures, proposing a simple switch block scheme can be directly applied to field programmable gate arrays (FPGAs), switch block designs, and communications switching networks designs. We present a new universal switch blocks with four sides and m terminals on each side, which is routable for every two-pin net-routing requirement. We also give a formal analysis and extensive benchmark experiments on routability comparisons between today’s most well-known FPGA switch blocks like disjoint switch blocks (Xilinx XC4000 Type), Wilton’s switch blocks, Universal switch blocks, and our universal switch blocks. To distinguish our design from Chang’s switch blocks, we name our universal switch blocks after Yen’s switch blocks, or YSBs for short. We apply the design scheme to rearrangeable switching network designs targeting for applications of connecting multiple terminals (e.g., teleconferencing). Simply using a 4-sided universal switch block with a mm crossbar attached to each side, one can build a three-stage one sided switching network capable of realizing every two-point connection requirement on m-terminals. Besides, due to the fine-grained decomposition property of our design scheme, the new designs are highly scalable and regulation on physical layout and routing algorithm implementations.

Nowadays, security requirements are increasingly important for private data transmission through mobile devices with Internet access, such as smart phones, which require an energy-efficient cryptosystem due to the limitation of battery capacity. Modular multiplication is widely used in public key cryptosystems. This thesis presents an energy-efficient block-based scalable Montgomery modular multiplication design. Using the proposed architecture mapping scheme and deferred scheme in dependency graph, not only reduces the switching activity of pipeline registers in kernel and memory access, but also supports any precision of operands. Experimental results based on TSMC 90-nm CMOS technology show that compared to the related works under the number of words larger than the number of processing elements, the proposed design achieves 8.2% to 59.1% energy reduction than related work for completing one Montgomery modular multiplication.

Linear guide and ball Screw are industrially important transmission components, both use rolling elements to achieve the purpose of the transmission. However, the rolling element will affect the machining accuracy due to thermal expansion deformation, which is an important problem that the precision machinery industry needs to overcome. The main purpose of this study is to design a cooling slider to improve the thermal expansion deformation of linear guides and maintain high production yield and processing quality. In this study, the cooling return line is designed inside the slider. At the same time, the cooling system is combined with the cooling equipment to form a closed cooling circulation system. By the circulation cooling system to reduce the heat transfer from the inside of the slider to the working platform, shortening the temperature to reach the steady state and the processing machine warm-up time. Through finite element analysis, the internal temperature distribution of the slider and the cooling slider is simulated. The experimental results show that the cooling slider has the effect of reducing the overall temperature of the slider and quickly reaching the steady state of the working temperature. During the experiment, the temperature variations between the slider and the cooling slide are analyzed at different speeds of 1 m/s, 1.5 m/s, 2 m/s and different load carrying capacities of 1200 kgf, 1400 kgf and 1600 kgf. As the speed increases and the load increases, the operating temperature of the steady state also increases. In contrast, the cooling slider can effectively lower the operating temperature while shortening the temperature steady state time.
