影响离合器使用寿命最重要的因素就是离合器工作时的表面温度。通过分析干式离合器压盘热力学环境,研究热量传导过程,提出轴向分层线性计算方法,并建立了温度估算模型,进而设计台架试验方案,通过台架试验获取转速,扭矩和表面温度等测量数据,利用Simulink模型离线仿真的方法对温度模型进行参数标定和估算温度校验,仿真结果表明该方法可较准确估算离合器压盘表面温度。

The most important factor affecting the service life of the clutch is the surface temperature of the clutch.Throughthe analysis of the dry clutch pressure plate thermodynamic environment,study on heat conduction process proposed axialhierarchical linear calculation method,and established the temperature estimation model,and bench test scheme is designed,by bench test access speed,torque and surface temperature measurement data,using Simulink model of the off-linesimulation method of temperature model parameter calibration and checking the temperature estimation.The simulationresults show that the method can accurately estimate the surface temperature of the clutch pressure plate.
