摘　　要：以计算流体动力学(CFD)及流固耦合数值计算理论为基础,对处于高速、高温、高压等高参数极端工况的机械密封摩擦副密封环界面、流体膜及工作流场进行了流固耦合数值计算分析,得到了流体膜流场特性及其对密封环变形、应力、应变的影响;并对圆弧槽动环动压机械密封与无槽动环静压机械密封的流体膜动力特性进行了对比分析,为高参数机械密封动环的进一步优化设计提供依据。Based on the computational fluid dynamics （CFD） and the fluid-structure coupling numerical computation theory, the characteristics of the flow field and its influence to the deformation, stress and strain of the seal ring were obtained through the overall numerical computation analysis of the fluid-structure coupling about the friction pair, oil film and working flow under high parameter complex working conditions such as high-speed, high-temperature and high-pressure. The comparative analysis of the dynamics charac- teristics of the opened circular groove rotating seal ring dynamic pressure mechanical seal and the slotless rotating seal ring static pres- sure one was made. The research results provide a theoretical basis for the optimized design of the rotatin~ rin~ of the mechanical seal.
