利用ANSYS软件,采用直接耦合方法,对带有周向槽和径向槽的摩擦片在滑摩过程中的温度场和应力场进行仿真计算和分析。在计算过程中考虑了摩擦片和对偶钢片摩擦所产生的热分配情况,以及摩擦片与沟槽内润滑油和外界空气的热交换,并同时考虑了各种位移约束。研究发现在滑摩过程中摩擦片的最高温度出现在摩擦表面,最高等效应力出现在沟槽内,两者的最大值出现在滑摩过程的中前期,数值分别为148.1℃和146 MPa;在每个小摩擦表面会形成椭圆热区,并且温度中间高,四周低;沿半径方向,半径越大,温度越高,小摩擦面上的温度分布为凸抛物线型,沟槽面为凹抛物线型。
Using ANSYS software, the direct coupling method was used to simulate and analyze the temperature field and stress field of the friction plate with circumferential groove and radial groove in the sliding process. In the process of calculation, the heat distribution caused by the friction of the friction plate and the dual steel plate is considered, and the heat exchange between the friction plate and the lubricating oil in the groove and the outside air is considered, and various displacement constraints are also considered. It was found that the maximum temperature of the friction plate appeared on the friction surface and the maximum equivalent stress appeared in the groove during the sliding test. The maximum values of the friction plate appeared in the early stage of sliding process and the values were 148.1 ℃ and 146 MPa respectively. At each small friction surface will form an elliptical hot zone, and the temperature in the middle of the high, low around; along the radius, the larger the radius, the higher the temperature, the temperature distribution of the small friction surface convex parabolic type, the groove surface concave parabolic type.
