| 摘 要： | 离合器在运行时产生的摩擦闪温是研究离合器热失效的重要参数。工程上通常采用热电偶埋入法测量离合器摩擦表面的温度。为了探究实际工况下离合器中温度场的分布，在真实测量时为传感器的选择和测点的布置提供有效依据。通过理论和有限元方法对干式离合器在某些工况下进行热分析，得到了该工况下钢片内距摩擦表面不同深度处的温度-时间曲线和钢片内部某深度处在不同压力、转速下的温度时间-曲线，并对各因素对温度的影响进行了分析。

| Abstract: | The friction flash temperature is an important parameter to study the thermal failure of the clutch. The temperature of clutch friction surface is usually measured by thermocouple embedding method in engineering. In order to explore the distribution of the temperature field in the clutch under the actual conditions, to provide effective basis for the choice of sensors and the arrangement of measuring points in real measurement. Thermal analysis on the dry clutch under certain conditions by means of theory and finite element method is performed to obtain the temperature time curves of the inner part of the sheet steel under different depths and the temperature time curves under different pressures and rotational speeds at certain depth. The effects of various factors on the temperature were also analyzed. |
