Fatigue life evaluation of disk brake of railway vehicle considering pressure distributions at frictional surface

摘要：

In this study, the thermal stress analysis was performed on a ventilated disk brake with a 3D model for two cases (whether the pressure distribution on a contact surface is uniform or not). A pressure distribution analysis was performed to determine the pressure distribution on the contact surface. Then, by using the results obtained from the pressure distribution analysis, the thermal stress analysis was performed. Also, for the life evaluation of a disk brake, the fatigue test was conducted and the S- N curve was obtained. From those results, the life of a disk brake was evaluated.
