摘要
本文通过非线性有限元软件MSC.Marc,计算了O形密封圈在密封槽产生短时间隙时的回弹过程。计算分别采用动力学计算和静力计算,并将两种计算结果进行了比较。本文还通过用户子程序考虑了外界压力对回弹过程的影响。
This paper presents a FEM model, on the case of MSC.Marc, to analysis the bounce-back process of O ring. And the results of two methods, transient response and static analysis, are obtained and compared. At last, user subroutines are used to simulate the effect of the outside pressure.
