The sliding process in the friction pair involves highly nonlinear behavior,and the temperature field of the friction pair is affected by numerous parameters.To gain a comprehensive understanding of the temperature field distribution in the friction pair of a hybrid electric vehicle clutch,a thermal structure coupling analysis model of the hybrid electric vehicle clutch was constructed to simulate the sliding process.Building upon this model,an in-depth study was conducted to analyze the impact of various parameters,such as initial speed,engagement oil pressure,dual steel plate thickness,and friction lining material,on the temperature field of friction pair.
