Title  Dynamics Analysis And Simulation Of Explosive Under
Launch Environment
Abstract
This departure is with the requirements of the engineering application,is taking PBX explosive as the main object of study.It has studyed the energetic mechanical behavior mainly from the dynamic mechanical properties under dynamic loads.Combined with experimental research ,theoretical studies,and mechanical analysis using finite element analysis of software ANSYS during the study.Because the energetic material constitutive relation is complex and it can be studied as a independent subject.Based on the purpose of this article is to study dynamics response of explosive under launch environment,so when choosing the constitutive relation of explosive we refer to previous study conclusions on the PBX explosive constitutive relation.Its main contents include the following aspects: 源自六;维,论/文.网*加7位QQ324`9114 www.lwfree.cn
Determining the experiment method of explosive blasting simulation under launch environment and the experimental data processing;Using finite element analysis of software ANSYS to simulate dynamics response of explosive under launch environment;Using the ANSYS numerical simulation to compare with the experimental results.
Keywords  Condensed explosives, dynamic mechanics performance,numerical analysis,Dynamics simulation
