The vibration of rolling discs
… investigation into the vibration of a rolling disc and an analysis of the sound which is then produced by the disc response. In order to characterise the disc's behaviour the free and forced vibration of a thin disc is analysed with the additional conditions which occur in rolling. …

Rolling contact orthopaedic joint design
… instead of bio-mimicry, to design prosthetic rolling contact joints, including knee braces, limb prosthetics, and joint prostheses, with the intent of reducing morbidity and complications associated with joint/tissue failure. A deterministic approach to joint design is taken to elucidating six …

Roll pressure distribution in strip rolling.
… 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 …

Fault detection of rolling element bearings
The early detection of bearing failure requires methods that are sensitive to impulsive signals and their changes. The difficulty of early bearing defect detection is that the signal component generated by early defect is very small compared to other vibration sources. It was found that techniques …

Vibration Extraction Using Rolling Shutter Cameras
… preferred. This study employs a consumer level rolling shutter camera for extracting main frequency components of small vibrations. A rolling shutter camera exposes continuously over time on the vertical direction of the sensor, and produces images with shifted rows of objects. We utilize the …

Multi-stable Compliant Rolling-contact Elements
… stable positions, the multistable compliant rolling-contact element(CORE). A CORE is a contact-aided complaint mechanism that eliminates friction and wear by allowing two surfaces to roll on each other. Furthermore, the contact eliminates problems such as poor performance in compression, …

Rolling contact fatigue of silicon nitride.
Silicon Nitride has traditionally been used as rolling contact bearing material owing to its superior performance compared to bearing steels. Its successful application as a bearing element has led to the development of Silicon Nitride in other rolling contact applications in the automotive …

The Impact of Rolling Dynamic Compaction
Rolling dynamic compaction (RDC) consists of a non-circular module of 3, 4 or 5 sides, that rotates as it is towed, causing it to fall to the ground and compact it dynamically. There is currently little guidance available for geotechnical practitioners regarding the depths of improvement that are …

Friction and lubrication in metal rolling
… 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 …

Effect of Vibration Foam Rolling and Non-Vibration Foam Rolling in the Lower Extremities on Jump Height
… whether a vibration stimulus combined with foam rolling yields better power output in the lower extremities during a countermovement jump (CMJ), than a group who uses foam rolling without vibration compared to no warm-up. Eighteen female and male participants, EWU athletes volunteered for this …

Mathematical modelling of asymmetrical metal rolling processes
… in the mathematical modelling of metal rolling processes, specifically asymmetrical sheet rolling. With the application of control systems in mind, desired mathematical models must make adequate predictions with short computational times. This renders generic numerical approaches …

Contact area between cylinders in rolling contact
The contact area between two rollers or cylinders was investigated both theoretically and experimentally. The theoretical investigation was based on Hertzian theory, while the experimental method used was based on the measurement of contact resistances. The variables in the investigation were the …

Tension regulation in a metal rolling mill
This thesis investigates the design of a strip tension regulator by analytical techniques. The tension transfer function is non-linear and is derived for two conditions, first with only elastic deformation in the strip, and second with plastic flow in the strip resulting from reduction in the roll …

A study of rolling adhesion in braking
The effect of normal load, contact velocity, and dwell time on the coefficient of adhesion at slip in braking was investigated. A test rig that simulated locomotive wheel/rail interactions was used for the experimentation. The results indicated a drop in the coefficient of adhesion with increasing …

Ship Rolling Motion Subjected to Colored Noise Excitation
… and probability density function of ship rolling are studied by nonlinear dynamic method and probability theory. The probability density function of rolling response is evaluated through solving the stochastic differential equations by using path integral method based on Gauss-Legendre …

ROLLING CONTACT FATIGUE BEHAVIOUR OF CASE-CARBURISED STEELS
… steel disc specimens as a result of rolling contact loading. The study of the surface topography of the run specimen using direct and indirect plastic replica technique and the electron microscope reveals cracks in the roughened area of the specimen and that excessively carburised …

Development Of Second Generation Rolling Contact Fatigue Tester
… The need for a second generation sliding-rolling contact fatigue tester was proposed by Gregory Dvorak and Dr. Marcellin Zahui. The first generation RCF tester was used for testing super finishing processes for gear surfaces. The second generation RCF tester was funded by the Advanced …
