摘要
参照国家标准设计了湿式离合器液压缸活塞密封圈,利用有限元分析软件Workbench建立了湿式离合器液压缸活塞密封圈模型,通过观察密封圈等效应力与接触应力云图对活塞沟槽和密封圈尺寸参数以及橡胶硬度进行了优化分析,仿真结果表明,改进后的沟槽和密封圈设计更加适用且密封圈橡胶的IRHD硬度宜在70~80选取,同时得出了湿式离合器液压缸作动过程中密封圈动静摩擦力的变化曲线,从而为湿式离合器液压缸的响应时间与控制策略的选择提供参考依据。
O-ring and piston groove were designed based on the national standard,and the models were compared in the finite element analysis software Workbench through modeling and simulation analysis. The sizes of the piston groove and the rubber hardness of O-ring were optimized by observing the equivalent stress and contact stress contours. The simulation results shown that the optimized size is more suitable and the international rubber Hardness Degree should be selected 70-80. The curves of dynamic friction and static friction were obtained at the same time, to provide reference for the response time and control strategy of wet clutch hydraulic cylinder.
