基于LS-DYNA的穿缸电连接器3O形密封圈的设计

Design of the 3O Sealing Ring of Wall-crossing Electrical Connector Based on LS-DYNA

穿缸电连接器应用于汽车双离合自动变速箱,密封圈是穿缸电连接器密封的关键零件之一。从密封圈的材料选择、关键尺寸确定、预压力的极限值等几个方面进行设计。采用LS-DYNA软件对密封圈对配过程的应力分布及装配力进行了CAE分析验证,满足设计要求。并对设计的3O形密封圈进行抗振动性、密封性、耐化学试剂性、耐高温老化性能综合实验评估,实验结果表明:设计的3O形密封圈满足业界标准,性能可靠,能够满足工业化生产的需求。

Wall-crossing electrical connector is widely applied to dual clutch transmission on vehicles; sealing ring is one of the critical components of wall-crossing electrical connectors. The sealing ring was designed from materials,critical dimensions and the critical magnitude of the pre-pressure. To meet the design criteria,LS-DYNA was used to conduct the CAE analysis on both the stress distribution and the assembly force in the process of distribution of the sealing ring. The comprehensive experimental evaluation was done on the designed 3O sealing ring. The evaluation included several items： vibration resistance,tightness,chemical resistance,and high-temperature aging resistance. The evaluation results show that the design is able to satisfy industry standards,be reliable,and meet the requirements of mass production.
