气密封高压试验爆炸模拟分析

Numerical Simulation of High Pressure Explosions with Air Seal Test

分析了气密封高压试件爆炸的物理过程,采用等效TNT药量爆炸替代气体爆炸,利用LS_DYNA对气密封高压试验爆炸过程进行数值模拟。通过对计算模型进行计算,获得了爆炸冲击过程的完整物理图像和防护钢板在爆炸冲击过程中产生的应力状况。计算结果为气体密封试验仓的防护结构设计和材料选择提供了理论依据。

This paper analyzes the physical process of gas seal high pressure explosion. Equivalent TNT is used to replace the gas seal explosions, and LS_DYNA is used to do numerical simulation of hermetically sealed high voltage test explosion process. We get the integrity process of physical images falling impact, and the stress conditions of protection plate in during the impact. Through steel stress analysis and calculation results, this paper provides a theoretical basis for the structure design and material selection. protective protective
