Research on the mechanical and sealing characteristics of metallic C-ring for reactor pressure vessels
为研究反应堆压力容器用金属C形密封环的力学及密封特性,采用有限元分析法对其进行模拟仿真,并与试验结果对比验证了模型的准确性和可靠性.在此基础上,分析了C形密封环所处温度、材料等参数对其压缩回弹特性曲线、回弹率、接触压力、接触宽度等力学特性和密封特性的影响.结果表明,C形密封环在高温环境下的压缩回弹性能和密封性能均差于常温环境;C形密封环各部分材质对其压缩回弹性能和密封性能存在影响,并提出了一组性能较优的材料组合,可为C形密封环的实际工程应用提供参考.
To investigate the mechanical and sealing properties of metallic C-ring for reactor pressure vessels,this study employed finite element analysis(FEA)to simulate their behavior and validated the model accuracy and reliability through experimental comparisons.Based on this,the effects of temperature and material parameters on the compression-rebound characteristic curves,rebound ratio,contact pressure,and contact width of the C-ring were systematically analyze…查看全部>>
