摘　　要：利用非线性有限元理论建立了某新型辅助密封圈的有限元模型;利用有限元软件MSC.MARC分析了该结构在安装和使用过程中的接触变形、接触密封界面上的接触应力分布及摩擦特性等。结果表明,该密封结构辅助密封性能好,能够承受较高压力,并且与轴之间的摩擦阻力小,耐磨性能好,适用于旋转密封以及往复密封。Finite element model of a new type auxiliary seal ring was established by using nonlinear finite element analysis, MSC. MARC was utilized to analyse the contact deformation, the distribution of contact stress within the sealing interface and the frictional property. The result shows that the type of auxiliary seal can provide good sealed property and can endure higher pressure. The seal has little friction force and good antiwear property, which can be applied to rotate and to- and-fro seal.
