摘　　要：针对一种插拔装置不能灵活分离的问题,使用有限元法计算并比较"Y"形、"L"形、"T"形与"O"形密封圈插入和拔出时结构与密封圈接触部位接触力,通过气密考核试验及分离力试验对计算结果进行验证。结果表明,异形密封圈密封性能良好,且能显著降低结构拆卸时的摩擦力,有利于结构拆卸灵活、顺畅。In order to solve the difficult separate problem of a type of plug seal structure, the finite element anal-ysis was used to calculate the interaction pressure of seal zone of ＂Y＂, ＂L＂ periment and separating experiment has been conducted to prove the finite sealing of shaped seal ring, The sealing ex-element results. The results show that the structure is finer and the structure can lower the friction of plug , which will lead to the separation flexible.
