Numerical Analysis and Test Research on Work Process of PSD in Pulse Solid Rocket Motor

Abstract:

To achieve engineering application of pulse motor as soon as possible,designed a soft pulse separation device(PSD), numerical simulated its process of bearing pressure and turning on,used the XFEM to simulate its failure form,got strain and stress distribution,found the bearing capability and failure form of the structure of soft PSD was reliable;Designed a few of verification monomial tests,verified the accuracy of simulation,proved that its bearing capability and failure form satisfied with design requirements,could be applied to pulse motor.The simulation technique,test method and conclusion are useful for designing pulse solid rocket motor configuration.
