摘要

Comparing five radial pressure distribution forms, the effect of radial non-uniform pressure distribution on thermo-mechanical coupling of wet friction pair was analyzed by means of finite element simulation and experiment. The results show that there is a strong coupling relationship among the temperature field, stress field and strain field of the dual steel sheet under the same radial pressure. At the end of the working state, the radial position of the temperature, stress and strain field and the maximum value of each physical quantity move to the center of the disk compared with the peak position of the original loading pressure, and the change rate of the radial position of the ring is 10%~40% of the disk width. The radial pressure distribution mode has a direct relationship with the temperature of the friction pair and the maximum value of stress and strain. When the pressure is distributed along the inner and outer radius wave crest, the value of temperature and strain is maximal. When the pressure is linearly reduced from the inner to the outer diameter, the value of stress gradually go to maximum. When the pressure changes along the inner diameter wave trough, the value of temperature, stress and strain is minimal.
