| 中文摘要: |
| 基于正交试验设计，利用Abaqus软件分别以密封面摩擦力和最大等效应力及静态泄漏量为优化目标，以4个关键结构参数（密封环径向厚度、密封唇与O形圈配合处径向厚度、密封倾角以及唇口与O形圈配合处高度）为优化对象，对VL密封结构进行优化分析。结果表明：密封环径向厚度对VL密封结构的摩擦力与泄漏量影响效果相反，由于泄漏量小会导致摩擦力大，其推荐取值为2.5 mm，但在对VL密封结构的摩擦力要求不高的场合可选择较大的密封环径向厚度；密封唇与O形圈配合处径向厚度对VL密封结构的泄漏量影响不大，其推荐取值为0.80～0.85 mm；密封倾角对VL密封结构的最大等效应力与泄漏量影响程度相差不大，应优先实现小泄漏量，其推荐取值为13°；唇口与O形圈配合处高度对VL密封结构的摩擦力、最大等效应力及泄漏量影响都不大，其推荐取值为1.05～1.15 mm。 |

| Based on orthogonal experimental design ，Abaqus software was utilized to conduct optimization analysis on the VL sealing structure，with friction force and maximum equivalent stress on the friction face and leakage under static conditions as the optimization objectives，four key structural parameters （radial thickness of the sealing ring，radial thickness at the mating area between the sealing lip and O-ring，sealing inclination angle and height of the mating area between the lip and O-ring） as optimization targetes.The results indicated that，the radial thickness of the sealing ring had opposite effects on friction force and leakage of VL sealing structure，considering that a small leakage leads to a large friction force，its recommended value was 2.5 mm.But the larger radial thickness of the sealing ring could be chosen in situation where the friction force of VL sealing structure requirement was not high.The radial thickness at the mating area between the sealing lip and the O-ring had little effect on the leakage of the VL sealing structure，and its recommended value was 0.80～0.85 mm.The influence of the sealing inclination angle on both the maximum equivalent stress and leakage of the VL sealing structure was not significantly different to prioritize achieving the small leakage，its recommended value was 13°.The height of the mating area between the lip and the O-ring had little effect on friction force，maximum equivalent stress and static leakage，its recommended value was 1.05～1.15 mm. |
