摘要

综合考虑摩擦片与工作介质油的对流换热作用,建立摩擦副混合摩擦阶段热结构耦合物理模型,采用有限元法对带有径向槽的摩擦片在混合摩擦过程中的温度场和应力场进行计算和分析。在相同工况下对比分析摩擦片表面沟槽的宽度和深度对摩擦片温度场的影响和应力场分布,研究发现摩擦片沟槽区的温度远低于摩擦接触区,接触区域的中心形成温度较高的热斑,摩擦片温度随着沟槽宽度的增加而降低,随着沟槽的深度增加先降低后增加。研究结果对液黏离合器运行过程中摩擦副温度场和应力场的预估及摩擦副的设计具有理论和工程指导价值。

Abstract

The heat convection of friction plate with oil film comprehensive is taken into account,the mixed friction process thermal structural coupling physical model of friction plate is established for simulation,the temperature field and stress field of friction plate with radial grooves during mixed friction process are simulated by using finite element method. The groove width and depth on the temperature field and stress filed of the friction plate are comparatively analyzed under the same conditions. The research results show that the temperature in the groove of the friction plate is much lower than that of the contact regions,and the center of the contact regions present a hot spot with higher temperature,the friction plate temperature decreases with the increase of the groove width,and first lower and then increased with the increase of the groove depth. The research results have engineering and theoretical guiding value for the prediction of the temperature field and stress field during the operation process of the hydro-viscous clutch and the design of the friction plate.
