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A1 B1 C1 D1；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。
對雙金屬自密封波齒墊片運用正交試驗方法設計瞭四因素三水平的試驗方案，採用有限元方法研究其壓縮迴彈性能，併比較相同結構參數下波齒複閤墊片與雙金屬自密封波齒墊片的密封性能。研究結果錶明：石墨覆蓋層厚度是影響雙金屬自密封波齒墊片壓縮率的顯著因素，縫寬是影響其迴彈率的顯著因素，雙金屬自密封波齒墊片的優選方案為A1 B1 C1 D1；相同預緊力下雙金屬自密封波齒墊片可以密封較高的內壓。

The study plot was planed with four factors and three grades adopting orthogonal experimental design method.The compressibility and resilience performance of the new gaskets was investigated adop-ting finite element analysis,the sealing performance was discussed between the new gasket and flexible graphite corrugated metal gasket.The result shows that the major element that greatly affects the compres-sibility and resilience performance of the gasket are graphite and gap;the excellent scheme is A1 B1 C1 D1;compared with the flexible graphite corrugated metal gasket,the new gasket has a better sealing perform-ance.
