摘要
本文建立了表面覆有聚酯纤维织物的橡胶密封件的气体泄露通道,结合有限元软件得到织物在受力变形后的气体泄漏率,提出仿真预测分析方法。并通过密封试验,验证了气体泄漏通道和仿真预测分析方法的正确性,为民用飞机密封件密封性能设计提供参考。
In this paper,the gas lea^ge passage of rubber seal coated with polyester fiber fabric is established.Combined with the finite element software,the gas leakage rate of fabric under stress deformation is obtained,and the method of simulation prediction analysis is put forward.The correctness of gas leakage passage and simulation prediction analysis method are verified by airtight test,which provides a reference for sealing performance design of civil aircraft seals.
