Numerical Simulation and Life Prediction of Steel Ball Unfolding Wheel Wear

Wear of sprag clutch wedge in overrun state under high temperature condition

“…Because the F-value of the lubrication is greater than that of F 0.05 (1,3), the lubrication has a significant influence on the wear depth within the given range. At the same time, the F-value of the temperature is greater than F 0.1 (2,3) and thus the temperature will also have a certain influence. However, the speed has only a small effect.…”

“…The amount of wear was found to increase with increasing sliding speed and increasing contact pressure. Pang et al 3 derived an equation to describe the relationship between wear depth and the amount of wear; they then simulated the wear of a steel nonrolling wheel using ANSYS software and predicted the wheel's wear life. Gromyka et al 4 proposed a method to evaluate wear of mining tools and another method to determine the remaining lifetimes of mining equipment and loader tools in a high temperature working environment.…”

“…Cai et al 8 performed both experimental and numerical analyses of polygonal wear in high-speed trains and found that the magnitude of the wear depth and the phase difference between the change in wear depth and the original polygon both play important roles in enlarging the polygon. Pang et al 9 analyzed the wear profile and the wear mechanism of a nonrolling wheel on a driving surface and then simulated the wear caused by a nonrolling wheel on a smooth surface and the microstructure of the nonrolling wheel surface using ANSYS software. The relationship between wear depth and the number of wear times was obtained and their model was validated using realworld examples.…”
