【摘要】 为了全面研究水介质爆炸容器在内部爆炸作用下,冲击波压力场的动态分布和壁部应变规律,本文利用动态数值模拟软件LS-DYNA,对水介质爆炸容器在内爆作用下内部动态压力场和壁部应变进行了三维数值模拟,并与实验和经验公式计算结果进行了对比。通过对数值模拟结果的分析,确定了爆炸容器结构强度在内爆作用下的薄弱区域。更多还原

【Abstract】 In order to study the dynamic response of the explosive container in aqueous medium under the internal explosion impact,the dynamic distribution of shock wave pressure field and the strain rule of the tank wall had been simulated with the help of the dynamic numerical simulation software LS-DYNY.And the numerical simulation results had been validated by the experimentation and experiential formula.Based on the analysis of the numerical simulation results,the position of the unsubstantial area in the container was fixed.更多还原
