| Abstract: | The research purpose is to simulate dynamic response of solid rocket motor(SRM) under axial impact load,and to provide some reference for the design of SRM.On the basis of modal analysis,the axial impact response was analyzed through finite element of displacement method.The calculated displacement,stress and strain are in good accordance with test results.It is concluded that finite element of displacement method is appropriate to analyze and calculate the dynamic response of SRM under axial impact load,and can provide reference for the design of SRM. |
