| 中文摘要 | 弹簧加强金属C形环是一种性能优良的静密封元件,为研究结构对C形环力学性能以及密封面接触特性的影响,建立弹簧加强金属C形环三维仿真模型,采用有限元方法分析C形环的压缩回弹特性。仿真结果与压缩回弹实验结果一致,验证了理论模型的正确性。分析C形环密封面上接触区域和接触压力的变化规律,讨论C形环结构对密封特性的影响。结果表明:在相同的载荷下,C形环卸载时的接触区域比加载时的大,表明在卸载阶段C形环在更低载荷下即可维持同等密封效果;螺旋弹簧使C形环具备良好的回弹性能,能更好地应对使用工况的波动;银层使法兰与密封环的接触界面实现良好密封,合金层起保护银层和平稳传递接触力的作用。; Spring energized metal C ring is an excellent static sealing component. To study the structural effects on C ring's mechanical properties and contact performance of the sealing interface,a three-dimensional model of the C ring was established and its mechanical properties and sealing mechanism were analyzed by finite elements method. The simulation results were validated by the compression-resilience test. Results show that the contact area of C ring is larger at the unloading stage than that at the loading stage,which indicates that C ring at the unloading stage has the same sealing performance under a relatively lower load. The coil spring offers C ring a good compression-resilience property to response to the fluctuation in working condition. The silver lining makes a good match between the contact interfaces of flange and C ring.The alloy lining plays a role in protecting the silvering lining and transmitting the contact force smoothly. |
