摘　　要：通过试验数据确定EPDM材料的两参数Mooney-Rivlin模型,建立Ο形密封圈和双拱形密封圈的有限元仿真模型,对比分析压缩率和介质压力对密封圈性能的影响,为密封圈的设计选型提供参考。The authors determine the Mooney-Rivlin model with two parameters of EPDM material through test data and establish the finite element simulation model of the O shape sealing ring and the double-arch shape sealing ring.They compare and analyze the influence of compression rate and medium pressure on the sealing ring and provide references for the design and selection of the sealing ring.
