Abstract:
This work aims to propose a novel design for quick return mechanisms, and the new mechanism is composed by a generalized Oldham coupling and a slider-crank mechanism. First, the kinematic dimensions that affect the time ratio are found by investigating the geometry of the proposed design. By transforming into its kinematically equivalent mechanism, and then the design equations of time ratio are derived. Furthermore, a design example is given for illustration. Moreover, the design is validated by kinematic simulation using ADAMS software. Finally, a prototype and an experimental setup are established, and the experiment is conducted. The results show that proposed new mechanism is feasible and with reasonable accuracy. In addition, it is more compact and easier to be balanced dynamically than a conventional quick return linkage.

Abstract:
This is the 11th research papers in a series of papers aiming at the optimal synthesis of planar mechanisms. The mechanism in hand is invented by Al-Jazari in the 12/13th century and is analyzed before by the author for a specific time ration, stroke and transmission angle. In the present work the mechanism is optimally synthesized for maximum time ratio and desired normalized stroke. Five functional constraints are defined to control the performance of the mechanism. The MATLAB optimization toolbox is used and four dimensions of the mechanism are assigned in a normalized form. Normalized stroke range from 1 to 5.45 is covered and the study shows that it is possible with Al-Jazari mechanism configuration to go to a time ratio as large as 6.3. The optimized synthesis of the mechanism can keep the transmission angle of the mechanism during complete crank rotation within a range from 45 to 116.7 degrees for the range covered for the desired normalized stroke.

Abstract:
Quick Return Mechanisms (QRMs) are one of the essential accessories used in machine tools which involve reciprocating cutting action with a quick return stroke and a constant angular velocity of driving crank. The aim of this work was to simulate, design and construct a prototype of a QRM that can be used for demonstration and instrumentation. The QRM was simulated using Solidworks and a prototype was developed from the simulated results. The experiment was conducted using the prototype. The kinematic simulation of the Solidworks model was compared with the kinematics of motion of the prototype. The result showed that the Percentage Stroke Length error was 0.36%. It was observed that, there was no significant difference in the simulated and experimental results, hence, the prototype can be used for demonstration and experimentation to assist students in understanding basic principles of the machine operation.

Abstract:
The dynamic response of an adaptive fuzzy neural network (FNN) controlled quick-return mechanism, which is driven by a permanent magnet (PM) synchronous servo motor, is described in this study. The crank and disk of the quick-return mechanism are assumed to be rigid. First, Hamilton’s principle and Lagrange multiplier method are applied to formulate the mathematical model of motion. Then, based on the principle of computed torque, an adaptive controller is developed to control the position of a slider of the quick-return servomechanism. Moreover, since the selection of control gain of the adaptive controller has a significant effect on the system performance, an adaptive FNN controller is proposed to control the quick-return servomechanism. In the proposed adaptive FNN controller, an FNN is adopted to facilitate the adjustment of control gain on line. Simulated and experimental results due to periodic step and sinusoidal commands show that the dynamic behavior of the proposed adaptive FNN control system are robust with regard to parametric variations and external disturbances.

The equations of motion in matrix form are formulated for a flexible rod in a quick return mechanism using Hamilton’s principle and the assumed mode method. The rod is considered as an Euler beam. The crank is assumed to be rigid and rotating at a constant angular speed. The translating-rotating joint connecting the crank to the flexible rod is assumed to be a frictionless moving point support for the flexible rod. This support is regarded as a very stiff spring acting on the rotating flexible rod. Results of numerical simulations are presented for various prescribed crank positions, crank lengths, and crank speeds.

Abstract:
碩士<br>國立成功大學<br>航空太空工程學系碩博士班<br>93<br>Dynamic response of a quick-return mechanism with a crack in the flexible linkage is investigated in this thesis. The flexible linkage of the system is modeled as a Timoshenko beam, which includes the effects of rotary inertia and shear deformation. The rigid crank drives the flexible linkage at a constant angular speed. The crack in the flexible linkage is modeled as a transverse open crack whose local flexibilities are calculated by using a fracture mechanics approach and the Castigliano’s theorem. The finite element method and Lagrange equation are employed to derive the equations of motion of the system. Dynamic responses are obtained by using the Runge-Kutta method. Influences on dynamic response of the system due to different depths and locations of the crack on flexible linkage are investigated.

Abstract:
碩士<br>中原大學<br>機械工程學系<br>87<br>The finite difference method (FDM) with fixed and variable grids is proposed to approximate the numerical solutions of a flexible quick-return mechanism, which involves a flexible rod with time-dependent length. In the dynamic analysis and simulation, the flexible rod is divided into two regions. Each region is modeled by the Timoshenko- and Euler-beam theories. It is found that (1) the fixed-grid method, where the moving boundary is often located between two neighboring grid points, breaks down when the boundary moves a distance larger than an increment space during a time step. (2) The possibility of break down can be avoided via the variable-grid method, in which a coordinate transformation is employed to fix the moving boundary. The numerical results are provided to compare with the previous works.

Abstract:
Abstract Despite major advances in contemporary macroeconomic theory, policymakers and citizens in most countries have been particularly frustrated by the inability of economists to provide reliable general blueprints and actionable policy frameworks to cure pervasive and persistent joblessness, which is perhaps the worse of economic and social ills. African economies such as Cameroon’s have suffered disproportionately from the consequences of this knowledge gap. While the range of market failures studied by economists over recent decades has been expanded to include market imperfections, they have not fully accounted for the implications of market failures in labor markets—including the prevalence of segmented markets that eliminate competition, or even the total absence of markets for certain skills or categories of workers. Relying on the miraculous fetichism of the price mechanism, conventional wisdom among economists has long viewed the labor market as mostly clearing or at worst in the process of quick return to market-clearing equilibrium. This chapter discusses the challenges to employment creation in developing country contexts—especially through industrialization—and offers a policy framework for creating employment.

Abstract:
Central venous pressure (CVP) is a measure of the mean pressure within the thoracic vena cava, which is the largest vein in the body and responsible for returning blood from the systemic circulation to the heart. CVP is a major determinant of the filling pressure and cardiac preload, and like any fluid pump, the heart depends on an adequate preload to function effectively. Low venous return translates into a lower preload and a drop in overall cardiac output, a relationship described by the Frank-Starling Mechanism. CVP is an important physiological parameter, the correct measure of which is a clinically relevant diagnostic tool for heart failure patients. In addition to other vitals such as heart rate and mean arterial pressure, accurate measures of central venous pressure through simple diagnostic instrumentation would provide physicians with a clear picture of cardiac functionality, and allow for more targeted treatment. Recent literature has also shown that measuring CVP can be an important hemodynamic indicator for the early identification and treatment of more widespread conditions, such as sepsis (Rivers, Nguyen, Havstad, &amp; Ressler, 2001). With over five million patients (American Heart Association, http://www.americanheart.org/presenter. jhtml) in the U.S. presenting with heart failure-like symptoms annually, a current challenge for physicians is to obtain a quick and accurate measure of a patient’s central venous pressure in a manner that poses minimum discomfort.

Abstract:
Proving ownership of the land should preferably be done with a legal document that proves it decisively. Many authorities retain various documents, any of which could be used to assert a claim on the land. To prevent document falsification, the land administration mechanism ought to be robust, accessible at all times, and quick to accomplish exercises. But, any such solutions are prone to a slew of issues, including data accuracy, security, and dispute resolution. Usage of blockchain technology in land administration is considerably advanced to solve issues that plague current LAS. With the adoption of blockchain, the problem of cooperation among a variety of land records is articulated. The proposed model has integrated units to digitally sign the land assets to store securely into the blockchain using cryptography algorithms after which land assets are verified. The proposed approach eliminates deception, improves administration. The results show that the time complexity for registering, signing, and verifying land facts to establish a system using blockchain is relatively secure.

Abstract:
The approach adopted in this work is an attempt to introduce students, in kinematics and dynamics of machinery course, to a complete design and analysis of function generation mechanisms via analytical methods. Although the approach implemented in this work is for function generation type of mechanisms, the concept is indeed extendable to the other types of mechanisms as well. As a project in the kinematics and dynamics of machinery class, students designed, and analyzed a four bar quick-return mechanism using MATLAB and SIMULINK as the primary software tools. One of the aims of this project was to abandon the traditional graphical synthesis and graphical analysis, covered in all the mechanisms textbooks, and to use the powerful combination of MATLAB and SIMULINK to implement the entire design and analysis process. The project, given to an undergraduate class, serves also as a prologue to future advanced courses in mechanical engineering, such as multi-body dynamics. In implementing the dimensional synthesis portion of the project, students employed complex number arithmetic to realize the design specifications. Once the design specifications were met, a known motor torque was applied to the crank to drive the mechanism. With the known geometric and inertial properties of each link, Lagrange’s equations for constraint motion were then utilized to arrive at the second order differential equations of motion. SIMULINK, as a user friendly graphical interface, was used to carry out the integration to obtain angular position, velocity, and acceleration of the designed mechanism. The project also calculates the reaction loads on the mechanism using the concepts of Newtonian mechanics. The project, though rigorous, is an excellent way to force students to practice their knowledge of dynamics and numerical methods. The project, certainly, meets the ABET criteria for implementing design in mechanical engineering curriculum. The author received positive feedbacks from his students with regard to this project.

Full text
Abstract:
Regarding the quick return mechanism, some researchers have neglected the rotor-mechanism coupling effect, and other researchers have combined the quick return mechanism with the motor but only considered the rotational motion of the rotor by assuming the rotor to be rigid and neglected the gear mesh dynamics. In the study, the rotor-mechanism coupling effect is investigated to find that the dynamic behaviors of the coupled system are different from those uncoupled systems. The coupling effect is mainly due to the flexibility of the shaft, the bearing, and the gear mesh. When the quick return mechanism is driven with the flexible geared rotor, the vibrations of the geared rotor have significant influences on the dynamic behaviors of the quick return mechanism. The traditional studies formulated the quick return mechanism only under the consideration of planar motion. However, the three dimensional vibration has to be considered for establishing the physical model of the coupled system. The main objective of this study is focused on the investigation of the coupling effect of the geared rotor on the quick return mechanism. The system model is formulated by using finite element method and following Hamiltonian approach. The numerical integration method is applied to obtain the dynamic response. The coupling effect of the geared rotor on the quick return mechanism is discussed by the parameter study. It is shown that the bearing stiffness and damping and the shaft radius have significant influences on the dynamic behavior of the mechanism.

Abstract:
Piezoelectric materials are being used to harvest mechanical energy from ambient vibration and convert it to electrical energy. They are mainly used to power miniature wireless sensors such as accelerometers, tachometers and proximity probes, which are commonly used for machine monitoring applications. However, exciting a piezoelectric cantilever with its resonance frequency for maximum power output remains to be a challenge. This is because the natural frequency of piezoelectric cantilevers is much higher than the common ambient vibrations. This study answers the research question: “Does a quick-return mechanism enhance the power output of a piezoelectric energy harvester?” For this purpose, analytical methods were employed to model a piezoelectric energy harvester mounted on a quick-return mechanism. The proposed mechanism was able to generate approximately 13.5mW of power, which is 35%–75% greater than the existing designs. A study on the working frequency range of the harvester for maximum power output was employed by varying the dimensional parameters of the quick-return mechanism. It was determined that by varying the dimensions of the quick return it is possible to harvest maximum power at a range of excitation frequencies. It was demonstrated that the system can effectively produce the maximum power when excited at frequencies ranging from 2rad/s to 46rad/s.

To solve each return would need a highly structured technique that requires extensive plot of results for the determination of proper failure mechanism.

A compilation of complete list of historical analysis with circuit block layout designation, test methods, signature cases, microprobing and circuit analysis collaboration results are consolidated in one file to help guide the Analyst in determining the exact cause of failure, thus improving quality and turnaround time that translates to cycle time improvement of 56% CT days reduction hence creating value to the customer.

Full text
Abstract:
Abstract Analytical precision position and optimum synthesis methods for linkages to generate specified force and torque histories are presented and applied to the planar four-bar mechanism. Mechanical advantage method (MAM) and integration of power equilibrium method (IPEM) are used to develop design equations. MAM yields design equations to use when the torque multiplication factor is defined at discrete number of design positions, as well as in continuous forms. IPEM requires continuous forms, but it reduces the torque generation problem into a function generation problem. Design equations with one, two, three, and four unknowns are developed for precision position synthesis; and they are used to formulate optimum synthesis process using many design positions that requires no iteration. Generation of infinite torque multiplication factor and synthesis of quick-return four-bar mechanism to generate specified advance-to-return time ratio are also considered. The synthesized four-bar mechanisms replace circular and non-circular external and internal gear drives. Several industrial application examples are included. The second part of the article considers the slider-crank mechanism.

The suggested machine uses the basic four bar chain mechanism and slotted lever type quick return mechanism with some modifications. The synthesis of the link lengths is based on Freudenstein’s (algebraic) three accuracy points. The velocity and acceleration analysis of oscillating links explains the effect of change in the crank’s angular velocity and acceleration on all other links. The suggested machine is capable of moving forward and backward, turning right and left and rotating around a point on the commands given.
