摘要：The wet clutch sliding friction process for a wet friction pair is simulated using the finite element method. Results allow examination of temperature fields and thermal deformation problems. Additionally, a test platform for wet friction joints and a temperature measurement system for wet clutch friction are established. Temperature data for a friction joint interface are analyzed. By comparing simulation results and experimental data, the distribution of radial temperature dif?ferences and circumferential temperature differences on a friction disk surface is analyzed. Results show that the maxi?mum temperature difference appears at the outer disk diameter position, increasing and then decreasing with bonding time. In the middle and late stages of total sliding time, the maximum radial temperature difference is twice the circum?ferential temperature difference. That is, the radial temperature difference is a major factor in failure due to friction heat. Both the finite element simulation and the experimental results show that hot spots are uniformly distributed along the circumferential direction at each radial position of the tip of the steel sheet.
