摘要
根据电控机械自动变速箱(Automated Manual Transmission,AMT)离合器特殊的结构形式,为了得到不同材料对AMT离合器摩擦副在特定工况下的温升影响。首先,建立离合器压盘和摩擦片的三维模型,分析AMT离合器的热传递物理模型,确定出离合器压盘与摩擦片的热边界条件;其次,利用ANSYS分析软件进行压盘和摩擦片瞬态温度场的仿真,得到不同材料的压盘和摩擦片温升曲线。最后,通过AMT离合器综合性能试验台对仿真结果进行了验证。研究结果对离合器的结构设计及材料的选择具有十分重要的指导意义。
According to the special structural forms of AMT clutch,in order to get the temperature rise characteristics of clutch friction with different material parameters under Specific conditions. Firstly,the 3D model of pressure plate and friction plates are established,the heat transfer physical model of AMT clutch is analyzed,the thermal boundary conditions of clutch is determined. Then,by using the software of ANSYS,the transient temperature field of pressure plate and friction plates are simulate,and the temperature rising curve is got. Finally,the simulation result of finite element analysis is verified through the AMT clutch comprehensive performance test bench. The results have important significance for AMT clutch structural optimization design and material selection.
