摘要
对双金属自密封波齿垫片运用正交试验方法设计了四因素三水平的试验方案,采用有限元方法研究其压缩回弹性能,并比较相同结构参数下波齿复合垫片与双金属自密封波齿垫片的密封性能。研究结果表明:石墨覆盖层厚度是影响双金属自密封波齿垫片压缩率的显著因素,缝宽是影响其回弹率的显著因素,双金属自密封波齿垫片的优选方案为A1B1C1D1;相同预紧力下双金属自密封波齿垫片可以密封较高的内压。
The study design method. The plot was planed with four factors and three grades adopting orthogonal experimental compressibility and resilience performance of the new gaskets was investigated adop- ting finite element analysis, the graphite co sibility and sealing performance was discussed between the new gasket and flexible rrugated metal gasket. The result shows that the major element that greatly affects the compres- resilience performance of the gasket are graphite and gap;the excellent scheme is A1B1C1D1; compared with the flexible graphite corrugated metal gasket, the new gasket has a better sealing perform- ance.
