热失效是混合动力汽车湿式离合器发生故障的主要原因之一。摩擦副滑摩过程中具有高度非线性，同时摩擦副温度场受到多个参数影响。为深入研究混合动力汽车离合器摩擦副温度场分布情况，通过搭建混合动力汽车离合器热结构耦合分析模型，对滑摩过程进行仿真计算。在此基础上，深入研究初始转速、接合油压、对偶钢片厚度和摩擦衬片材料等因素对摩擦副温度场的影响。

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.
