摘　　要：为了研究槽口圆角和预压缩量对密封效果的影响,利用ANSYS软件的Workbench模块建立了O形橡胶密封结构模型,分别讨论了在预密封和工作压力下密封圈的等效应力、剪切应力和接触应力,并分析了随着槽口圆角和预压缩量的变化,密封圈最大剪切应力和接触应力的变化规律。将槽口圆角和预压缩量同时作为参变量,考察得到密封圈最大剪切应力和接触应力的变化规律。In order to study the influence on seal of amount sealing O-ring section model is established using workbench of compression and slot corner, rubber tool of ANSYS software. The Von Mises stress, shear stress and contact stress in amount of compression and working pressure were calculated. Regular pattern of maximum shear stress and contact stress were analyzed in various amount of compression, slot corner and both as variable at the same time.
