Abstract:To study the influence of residual stress and strain hardening produced by manufacture process on compression and resilience performance of corrugated metal gaskets,a finite element analysis method of compression and resilience process for corrugated metal gaskets was established,which considered the effect of residual stress caused by manufacture process and is based on the experiments.By comparing the analysis results with the experimental results,it is shown that the finite element calculation results are in good agreement with the experimental results,the error of the maximum compressive load is 9.08%,the error of compression rate is 9.08% and the error of resilience is 13.90%.The deformation mechanism was analyzed by dividing the deformation process of the corrugated metal gasket into three stages according to the finite element calculation results,and the compression and resilience process of the corrugated metal gasket under the axial load was studied.The result shows that elastic deformation,plastic yielding and elastic recovery stages of corrugated metal gasket occur under the axial load.
