The study on numerical simulation of non-contact explosion impact response

摘要

It is a hot topic that how to calculate equipment response of non-contact explosive impact.Through theoretical analyzing the problem of some expert’s research about shock wave,and studying non-linear FE software LS-DYNA and AUTODYN in depth,the paper put forward a method to analyze impact response of equipment by using LS-DYNA and AUTODYN software.The paper used LS-DYNA load sub function to simulate explosive impact of different conditions,and analyzed the calculated result deeply by AUTODYN.The simulate results of actual equipment showed that the method integrated the advantage of two software and ensured high calculating accuracy.This method also could decrease much time used in creating different explosive condition models and increase efficiency than normal analysis procedure.t
