摘　　要：针对普通橡胶因磨损严重不适用于中、高压或真空密封的问题,采用纳米锶铁氧体磁性丁腈橡胶复合材料设计密封,研究不同后唇角与密封唇口最大接触应力的关系。仿真和试验结果表明,后唇角对油封的稳定性起着重要的作用,当系统压力较大时,后唇角宜取较小的值,系统压力较低时,后唇角可以适当取大点。Since ordinary rubber is not applicable to medium or high-pressure or vacuum seal because of wear. Nano-SrO·6Fe2O3 MNBR was used to design sealing structure, the relation of maximum contact stress and different posterior lib angle for sealing ring was studied. The simulation and experimental results show that the posterior lib angle plays an important role for the stability of oil seal. The value of the posterior lib angle should be smaller as the pressure of system is higher.
