| 中文摘要: |
| 以水下工作的旋转轴唇形橡胶密封圈（简称唇形密封圈）为研究对象，基于有限元分析方法研究安装过盈量和介质压力对唇形密封圈密封性能的影响。使用ANSYS软件创建唇形密封圈的三维轴对称有限元分析模型。仿真结果表明：唇口接触宽度与最大接触压力随着安装过盈量的增大而增大，且安装弹簧的唇形密封圈接触宽度和接触压力比未安装弹簧的唇形密封圈大；随着介质压力的增大，唇口最大接触压力增大，接触压力的最大值出现在唇口尖端处，最大接触压力始终大于介质压力。 |
| 英文摘要: |
| The rotating shaft lip rubber seal ring working under water was studied.Based on the finite element analysis method，the effects of installation interference and medium pressure on the sealing performance of the lip rubber seal ring were investigated.A three-dimensional axisymmetric finite element model of the lip ring seal was set up using ANSYS software.Simulation analysis showed that，the contact width and maximum contact pressure at the lip increased with the increase of the installation interference，and the spring-loaded lip seal ring had a larger contact width and a greater contact pressure than the lip seal ring without spring.With the increase of the medium pressure，the maximum contact pressure at the lip increased.The maximum contact pressure occurred at the tip of the lip and it was always greater than the medium pressure. |
