Abstract:
The dependence of rolling friction on velocity for various contact conditions is discussed. The principal difference between rolling and other types of relative motion (sliding and spinning) is that the points of the body in contact with the support change over time. Due to deformations, there is a small contact area and, entering into contact, the body points have a normal velocity proportional to the diameter of this area. For describing the dependence of the friction coefficient on the angular velocity in the case of “pure” rolling, a linear dependence is proposed that admits a logical explanation and experimental verification. Under the combined motion, the rolling friction retains its properties, the sliding and spinning friction acquiring the properties of viscous friction.

Abstract:
This article discusses features of a new friction management system, which is intended to boost efficiency on the railroad. Friction Management Services LLC of West Chicago, Illinois, has developed a friction management system, called TracGlide that consists of a synthetic polymer and computerized application equipment, installed on the locomotive at the front of the train. Unlike conventional lubrication schemes, the TracGlide system applies a friction modifier, not a lubricant, to the top of the rail. Although railroads usually avoid treating the tops of rails to avoid traction problems, the TracGlide polymer tends to increase the coefficient of friction when needed. The friction modifier is applied on both rails after the last axle of the last locomotive at the front of the train passes by. The application is computer controlled, based on factors such as the train’s weight, track curvature, speed, and temperature of the lubricant, which are constantly changing.

Abstract:
Friction property plays an important role in the operating process of engine, the analysis and discuss about friction property can help to improve the operating performance of engine. Based on the basic structure of swash-plate engine, the sphere rolling friction model and the roller rolling friction model were established, and corresponding formulae of the rolling friction force and the rolling friction coefficient were deduced. Then as an application, we employed the exact parameters of a swash-plate engine to calculate the sphere rolling friction force, the sphere rolling friction coefficient, the roller rolling friction force and the roller rolling friction coefficient. According to comparison, we concluded that roller rolling friction force was far less than sphere rolling friction force, and roller rolling friction coefficient was far less than sphere rolling friction coefficient. Furthermore, we proposed two topics which would be our next study concerning engine friction property: friction-induced heat, and high temperature influence on friction property.

Abstract:
A theory of cold rolling of thin gauge strip is presented which, within the idealizations of homogeneous deformation and a constant coefficient of Coulomb friction, rigorously models the elastic deformation of the rolls and the frictional traction at the interface. In contrast with classical theories (3) it is shown that, for gauges less than a critical value, plastic reduction takes place in two zones, at entry and exit, which are separated by a neutral zone in which the rolls are compressed fiat and there is no slip between the rolls and the strip. Roll load and torque are governed by five independent non-dimensional parameters which express the influence of gauge, reduction, friction and front and back tensions. Values of load and torque have been computed (for zero front and back tensions) for a wide range of thickness, reduction and friction and have been found to collapse approximately on to a single master curve.

Abstract:
This article presents the results of an experimental investigation of the frictional resistance arising in a drawbead during sheet metal forming. The frictional characterization of DC04 deep drawing quality steels commonly used in the automotive industry is carried out using a friction simulator. The effects of some parameters of the friction process on the value of the coefficient of friction have been considered in the experimental investigations. The friction tests have been conducted on different strip specimens, lubrication conditions, heights of drawbead and specimen orientations in relation to the sheet rolling direction. The results of drawbead simulator tests demonstrate the relationship that the value of the coefficient of friction of the test sheets without lubrication is higher than in the case of lubricated sheets. The lubricant reduces the coefficient of friction, but the effectiveness of its reduction depends on the drawbead height and lubrication conditions. Moreover, the effectiveness of the reduction of the coefficient of friction by the lubricant depends on the specimen orientation according to the sheet rolling direction. In the drawbead test, the specimens oriented along the rolling direction demonstrate a higher value of coefficient of friction when compared to the samples cut transverse to the rolling direction. The smaller the width of the specimen, the lower the coefficient of friction observed. The difference in the coefficient of friction for the extreme values of the widths of the specimens was about 0.03–0.05. The use of machine oil reduced the coefficient of friction by 0.02–0.03 over the whole range of drawbead heights. Heavy duty lubricant even reduced the frictional resistances by over 50% compared to dry friction conditions. The effectiveness of friction reduction by machine oil does not exceed 30%.

Abstract:
Abstract This paper describes experimental and analytical studies of the dependence of tire friction on the surface roughness of pavement. Abrasive papers were adopted as representative of the microscopic surface roughness of pavement surfaces. The rolling∕sliding friction of tire tread rubber against these abrasive papers were measured at low slip velocities. Experimental results indicated that rolling∕sliding frictional characteristics depended on the surface roughness. In order to examine the interfacial phenomena between rubber and the abrasive papers, real contact length, partial slip, and apparent friction coefficient under vertical load and tangential force were analyzed with two-dimensional explicit finite element analysis in which slip-velocity-dependent frictional coefficients were considered. Finite element method results indicated that the sum of real contact area and local partial slip were larger for finer surfaces under the same normal and tangential forces. In addition, the velocity-dependent friction enhanced local slip, where the dependence of local slip on surface roughness was pronounced. It proved that rolling∕sliding friction at low slip ratio was affected by local frictional behavior at microslip regions at asperity contacts.

Abstract:
Cette thèse porte sur l’amélioration du laminage à chaud, un procédé de fabrication sidérurgique permettant de transformer une brame de métal (10m de long, 1.5m de large et 250mm d’épaisseur) en une bande de tôle bobinée (1000m de long, 1m de large et 2mm d’épaisseur). Afin d’obtenir certaines propriétés mécaniques et de faciliter la phase de laminage, la brame est réchauffée à 1300°C et dégrossi avant d’être envoyé vers le train finisseur où elle est laminée en passant successivement dans plusieurs cages (ensemble de cylindres qui écrasent le métal) et qui permettent de réduire l’épaisseur à la valeur finale souhaitée. Le produit est finalement refroidi puis bobiné avant d’être envoyé au client. La thèse se focalise sur l’amélioration du train finisseur en proposant un contrôle du frottement entre la bande et les cylindres de travail à l’aide d’une lubrification. La lubrification consiste à déposer de l’huile sur le cylindre en vaporisant une émulsion d’eau et d’huile. L’huile déposée modifie l’interface entre la bande et le cylindre et diminue le coefficient de frottement. Cette diminution du coefficient de frottement a plusieurs avantages : elle permet de réduire l’usure des cylindres, d’améliorer l’état de surface de la bande, de réduire l’effort nécessaire de laminage donc la consommation d’énergie et d’augmenter la capacité du train. A l’inverse, un frottement trop bas dû à une lubrification trop importante peut causer un patinage de la bande entrainant l’arrêt du train. Il est donc important de contrôler le niveau de frottement de manière sécurisée. La conception du contrôle s’est faite à travers deux principales étapes : La modélisation et l’identification de l’effet de la lubrification sur le coefficient de frottement, la conception du contrôle du frottement
This thesis is about the improvement of the hot rolling process. This steelmaking process turns a slab (10m long, 1.5m wide, 250mm thick) into a coiled strip (1000m long, 1m wide, 2mm thick). To obtain some metallurgical properties and to make the rolling easier, the slab is heated up to 1300 ° C and roughly rolled before going to the finishing mill. In the finishing mill the strip is rolled through successive stands (set of rolls) to reduce the thickness to its final desired value. The product is finally cooled down and coiled before shipping it to the customers. The thesis focuses on the enhancement of the finishing mill through a friction control between the strip and the work rolls using lubrication. The lubrication consists in building up oil on the rolls by spraying an emulsion of water and oil. The deposited oil changes the contact interface between the strip and the roll and decreases the friction coefficient. The reduction of the friction presents the advantages of: reduce the roll wear, enhance the strip surface quality, decrease the rolling force (reduce then the energy consumption) and increase the mill capability. In the other hand, an insufficient amount of friction due to an overabundance of lubrication can induce a slippage of the strip leading to a stop of the mill. It is important to control the amount of friction in a secure way. The design of the controller was done through two main steps: Modeling and identification of the effect of lubrication on the friction coefficient, designing the friction control

This thesis presents an optical method to measure the rolling friction coefficientsfor balls rolling freely on a cylindrical surface. Two different models of a ball rollingfreely on a cylindrical surface are established, one is an analytical model and the otheris a numerical model derived from Lagrange equation. The rolling friction coefficientsare evaluated from the position data of the steel balls. The positions data are retrievedfrom images recorded by a high-speed camera. The locating algorithms includingbackground subtraction and ball recognition are presented in detail. The rollingfriction coefficients between different diameter steel balls and a cylindrical aluminumsurface are measured. The angular positions of the balls are predicted by the solutionof the equation of motion (EOM), and good agreements are found between theexperimental and theoretical results. The values of rolling friction coefficientsbetween different diameter steel balls and a cylindrical aluminum surface areevaluated.

Abstract:
This dissertation is concerned with the physical processes which determine friction and lubrication in metal rolling in the mixed lubrication regime, with particular attention paid to the conditions encountered when rolling aluminium foil. Two areas of relevance to the analysis of the rolling process are initially investigated. Firstly, the rheological properties of a typical aluminium foil rolling oil at high pressures and shear rates have been measured using a disc machine. The behaviour of the oil was found to be well described by the Eyring viscous model, at the shear rates and pressure likely to be found in metal rolling. Secondly, the deformation of asperities when the bulk material is deforming has been examined. The theory developed here was found to agree reasonably with experiments. The results of these investigations are used in the analysis of lubrication in metal rolling, considering the hydrodynamic buildup of oil pressure in the entry region and the crushing of the asperities both in the entry region and at the beginning of the work zone. The contact between roll and strip is divided into two regions, that under the asperities and that in the intervening valleys. Calculations for conditions appropriate to strip and foil rolling give the proportion of the two types of contact and the film thicknesses in each region. Measurements of film thicknesses with an experimental mill in a regime where roughness is unimportant were not found to agree well with an existing simple theory of lubrication. This was ascribed to uneven lubrication in the experiments. After taking this into account, the experiments in a regime where roughness was important were found to agree reasonably with the theory developed here. The effect of roughness on traction is measured in a disc machine with elastic contacts. Its behaviour is found to be determined by the bulk properties of the lubricant at the pressures and strain rates under the asperities. Theory and experiments presented in this dissertation lead to a greater understanding of the physical processes determining friction in metal rolling in the mixed lubrication regime. Film thicknesses and friction coefficients in metal rolling may now be estimated with more confidence.

Full text
Abstract:
The determination of the pressure distribution generated along the arc of contact between the rolls and workpiece during the rolling process has been a subject of interest to researchers for many years. Existing rolling theories make assumptions and include simplifications which are not often substantiated by direct measurement techniques in which pressure transducers are located within the roll surfaces. Such techniques are effective but prohibitively expensive since they render the rolls useless for rolling. A technique has been developed in which the pressure distribution and roll separating load are determined from consideration of the elastic deformation of the rolls during operation. By interrupting a rolling pass before completion, the shapes of the deformed rolls are imparted to the workpiece surface. Accurate measurement of the imparted profiles at several sections across the width of the workpiece allows the extent of the elastic deformation of the roll to be determined. An analytical solution based on solid body contact theory was used to determine the pressure distribution responsible for the elastic deformation along each section. The solution incorporates experimentally determined parameters and functions relating to specific mill-stands and schedules. Initial experimental work was undertaken in which the proposed technique was applied to the quasi-static indentation of flat and inclinedstrip specimens. Having established the basic features of the method relating to these modes of deformation the technique was then applied to the cold rolling process in the form of interrupted rolling passes. Tests were undertaken using a two-high laboratory rolling mill reducing the thickness of mild steel strip workpieces. Comparisons between the predicted pressure profiles using the technique developed and those determined by others using pressure transducers show close similarities. A comparison between the predicted roll separating loads and those determined experimentally show a reasonable correlation.

Abstract:
Friction is one of the most significant physical phenomena influencing metal forming, yet in comparison with metallurgy, heat transfer and mechanics it remains the least understood. The goal of this project was to develop, on as fundamental a level as possible, a friction model based upon the physics of the process to be applied to the hot rolling of steel. A fundamental friction model was developed based upon the simplified approach to the adhesion theory by Straffelini (Wear, 249, 79-85, 2001), which is an extension of Bowden and Tabor's original adhesion theory. In this work, the simplified approach's dependence on the thermodynamic work of adhesion was exploited to apply it over a wide range of temperatures. The thermodynamic work of adhesion describes the work required to form a new surface and is a function of the surface energy of the contacting materials was estimated using two approaches: Rabinowicz's and the geometric mean rule. Since high temperature surface energy data is not generally available the relative change in Young's modulus with temperature was used to estimate a material's surface energy at a desired temperature. Reciprocating friction experiments, which provided a controlled environment in which to investigate friction, were conducted to verify the application of this theory to high temperature conditions and metal-oxide contacting materials. The fundamental model describing friction was applied to the hot rolling of steel via a friction algorithm using the commercial finite element (FE) code MARC. Simply described the friction algorithm calculated a friction coefficient using material properties, defined by the user, and contact temperatures, taken from the rolling model. This resulted in the friction coefficient predicted throughout the roll bite, compared to an average friction coefficient typically employed in rolling models. The combined friction algorithm-rolling model was validated against laboratory rolling experiments. One of the assumptions of the finite element rolling model is the presence of a thin, continuous and adherent scale layer. To achieve this in the laboratory a two pass rolling schedule was employed; the first pass to remove the furnace scale and the second pass to input the desired deformation. The success of the friction algorithm was determined by comparing the experimental torques and loads to the predictions of the finite element model. The FE model with the friction algorithm predicted the friction coefficient to vary in the roll gap between approximately 0.25 and 0.35 and was able to predict the measured rolling torque with an average error of 15%, which was considered acceptable and the accuracy was increased after the bearing torque was considered. The error in the load predictions compared to the measured loads was 13.5% on average, which was also acceptable.

Abstract:
The purpose with this thesis was to examine the cold rolling mill located at Högskolan Dalarna and to stabilize the rolling process, to achieve steady state. Experiments with cold rolling of an aluminium strip have given results for rolling force, friction, reduction, strip tension and strain hardening. Results show that steady state has been found for the experiments with roll force and strain hardening, and not been found for the experiments with friction and reduction. Results show that increased strip tension gives lower roll forces. The roll force equation of Stone shows comparable results with reality for dry contact with reductions up to 30 %, but starts being incomparable with higher reductions. The roll force equation of Stone shows a bit higher roll forces than reality gave, but was comparable within reductions from 13 to 50 %. Experiments have shown that the aluminium strip has gone through strain hardening. Experiments show how the set roll gap did not yield the desired thickness reduction, there for the elastic spring constant for the rolling mill was examined and determined to be 417 N / mm for the specific alloy band. The influence of tension strip for roll force was examined and Results confirm the theory about how the roll force is decreased by increasing tension strip. The work rolls started to slip against the alumina strip as high tension strip; 70 N/mm2, gave low roll force; < 15kN.

Abstract:
The automotive industry is constantly being challenged by customers and authorities to enhance the efficiency of the internal combustion engine (ICE) in order to achieve improved fuel consumption and reduced emissions. There are several interfaces within the design of an ICE that causes frictional losses, one of them is the valvetrain. An approach to reducing the friction in the valvetrain of modern engines is to implement cam-follower rollers, resulting in a rolling rather than sliding contact when interacting with the camshaft. The prominent type of wear in rolling contacts is surface fatigue, and specifically a phenomenon called micropitting. The company in collaboration with this project is Applied Nano Surfaces Sweden AB (ANS), located in Uppsala, Sweden. The company have specialized in surface treatment methods of mechanical components. ANS has developed a mechano-chemical treatment method called ANS Triboconditioning, which have shown beneficial friction and wear reducing properties when applied to metal surfaces. This thesis was conducted to investigate how the ANS Triboconditioning would affect the frictional behaviour compared to established surface treatment methods and the occurrence of micropitting in rolling contact configurations. Two types of test programs was implemented into a Wazau UTM 2000 Twin-Disc Tribometer. No clear trend could be established from the micropitting tests and therefore no conclusion regarding if ANS Triboconditioning affects the occurrence of micropitting damage in a positive or negative manner could be stated. The results from the friction test indicated an overall reduction in friction for the test specimens that had been treated with ANS Triboconditioning when compared to specimens that only had been treated with already established surface treatment methods. Summarized, additional tests and analyses are necessary in order to statistically confirm the observed results and determine their respective trends.

Abstract:
Precision surface finishes are used in a wide variety of applications. From bearing races and rolling elements to parallel slide ways, the frictional characteristics of these surfaces are critical to the performance of the products. Experimental trial and error has shown that certain surfaces outperform others in certain applications, but the specific surface characteristics that make this true have yet to be fully understood. The research goal was to develop an apparatus that can test the coefficient of rolling/sliding friction of different precision machined surfaces and to combine this data with topographic analysis of the surfaces to correlate specific 3-D parameters with the frictional performance of a surface. The sample treatments consisted of four different surface textures (hard-turned, ground, honed and isotropic finish) and four different relative surface speeds. By monitoring the torque in the sample-mounting shaft under lubricated conditions the coefficient of rolling/sliding friction of each surface was found. Utilizing white light interferometry measurement of the surfaces, a highly detailed map of each surface was obtained. Using different characteristic values of each machined surface (RMS roughness, asperity density, lay direction, etc.), the frictional behavior of the surfaces were compared to the surface characteristics yielding insight into the relationship between surface finish and friction in rolling/sliding contact. Friction coefficient was found to correlate most strongly with RMS roughness (Sq) and density of surface summits (Sds). These parameters govern mechanical interference of asperities and surface adhesion respectively. These findings suggest that friction coefficients of surfaces could be optimized through manipulation of three-dimensional surface parameters.

Abstract:
Although, it seems that the concepts of static friction, sliding friction and rolling friction are common knowledges, their real sources are ironically not so clear. Inappropriate descriptions of them may have hampered the theoretical analyses and calculations of the frictions and deterred their applications in real world. In this paper, we are proposing a new method to model the static friction, sliding friction and rolling friction by three mechanical elements: spring, translatory damper and rotary damper respectively. It is shown that proper descriptions of the frictions, e.g. rolling friction, can help in correcting discrepancies in previous research works.

Abstract:
Abstract Linear ball guideways are widely employed in machine tool drive systems. Friction fluctuation of linear ball guideways cause the fluctuation of feed rate which results in the contour error in synchronous motions using several feed drives. A model-based systematic methodology to design the raceway profile is demanded to reduce the friction fluctuation of rolling guideways. In this study, a model to estimate the rolling resistance fluctuation of a ball sandwiched by two raceways was proposed. The rolling resistance fluctuation was estimated from the contact angle between the ball and raceways. The contact angle was obtained from the surface profile of the raceway. The estimation accuracy of the proposed model was verified by comparing measured and estimated rolling resistances. The raceway that was finished by face milling with a R-bite was used in the experiment to have rolling resistance fluctuation due to a periodic surface profile. The experimental results showed that the rolling resistance fluctuation could be estimated by the proposed model with 30% amplitude error at maximum. The variation of the rolling resistance was influenced by the phase difference between the upper and lower raceway profiles. The rolling resistance variation could be decreased to 1/3 when the phase difference was 1/2 period of the periodic profile component.

Abstract:
In order to investigate the validity of a coupled mill vibration model presented in the dynamic rolling formulation, this paper presents the results of dynamic characteristics examining rolling force variations in response to rolling parameters. Under the given steady state rolling condition, the unstable vibrational modes with corresponding frequencies are identified and stability analysis is also performed to demonstrate that the proposed model is highly dependent on the rolling speed and friction coefficient with an assumed negative gradient of friction coefficient. To further find the transient characteristics and the direct influences of the friction coefficient and rolling speed on the mill chatter, the derived equations of motion of the system are solved using Runge-Kutta numerical integration method. Simulations are carried out to reveal the chatter sources, which gives rise to unstable rolling vibrations.

Abstract:
This paper gives an overview of pre-sliding and pre-rolling friction, showing that it is characterized by rate-independent hysteresis with nonlocal memory. The dynamic behavior in this region can be described by a ‘damping ratio’. The scaling law in the normal force is discussed.
