摘　　要：基于ANSYS软件平台,对高性能旋转动密封环流场进行了数值仿真分析与计算,研究了高性能旋转动密封环圆弧槽槽形结构和圆弧槽几何结构尺寸与密封环液膜压力和剪切应力之间的关系,由此得出了高性旋转动密封环设计准则,采用该准则设计、制造的高性能旋转动密封环通过了坦克专用传动系统密封试验台密封性能和密封可靠性试验考核,试验结果表明,高性能旋转动密封环满足设计与使用要求。Based on ANSYS software platform, numerical simulation analysis of flow field of the high-performance rotary sealing ring is carried out, and the relations among the sizes of the arc groove sulciform structure and arc groove geometric structure, liquid film pressure and shear stress are studied for the high-performance rotary sealing ring. Based on this, the design criterion of high-performance rotary sealing ring was obtained. A high-performance rotary sealing ring made according to the criterion passed the test of sealing performance and reliability on the sealing test-bed for tank＇s special drive system. The test result shows that the high-performance rotary sealing ring can meet the requirements of product design and application.
