摘要
以综合传动装置中的湿式换挡离合器为研究对象,开展对偶钢片和摩擦片的热负荷仿真研究.考虑了摩擦接触、热弹变形等边界条件,基于ABAQUS6.7建立了湿式换挡离合器总成的三维有限元模型.揭示了摩擦片和对偶钢片在滑摩过程中温度场及应力场分布规律:其中盘面中部温升不明显,盘面两侧边缘温升明显,对偶钢片上的应力值随半径的增加而增大.接触面不同区域的应力值随时间变化的规律不同,内环节点的应力值先增大后下降,外环节点的应力基本上一直增大.
Aimed at a wet clutch in power shift transmission as the research object, the effects of thermal loads on the contact surfaces of dual steel disk and frictional plate were simulated. Considering the boundary condition of frictional contact and thermo-elastic feature factor in the friction disk, a 3D FEM model of clutch pack was set up by using software ABAQUS 6.7. Simulation was implemented to explore the distribution laws of temperature field and stress field on the contact areas between steel disk and friction plate. Results show that the increase of temperature of steel disk in the margin area is bigger than that in the inner area. The stress on the steel disk increases with the increase of radius value. The stress on different contact areas changes differently with sliding time. The stress value of nodes on inner circle increases first and decreases later, while the stress of nodes on outer circle is increase with the time.
