摘要

针对中心装药的冲击波加载研究了柱形爆炸容器的动力响应问题.模拟运用ANSYS/LS-DYNA软件

采用流固耦合方法

得到了爆炸容器壳体在爆炸中心点对应处的残余变形

并与实验值进行比较;绘制了壳体上一些特征点的等效塑性应变曲线和应力峰值曲线

分析了容器材料的应变率效应.结果表明:塑性变形主要集中在爆心附近区域;TNT药量越大

塑性区域与塑性变形越大;容器爆心环面的应力是最大的;应变率效应使壳体材料的屈服极限提高了2.2倍.

Abstract

In a cylindrical vessel

the dynamical response induced by a centrally charged blast wave was numerically studied.By using finite-element program ANSYS/LS-DYNA

which can deal with fluid-solid coupling algorithm

the residual deformations of the shell in the explosion center were obtained and compared with the experimental data;the plastic strain curves and the stress peak curves of several characteristic points on the shell were presented;the strain-rate effect of the vessel material was also analyzed.The results show that the plastic strain areas are in the vicinity of the vessel′s center.The bigger TNT mass is

the larger plastic strain areas and plastic deformations are.The stress of the plane across the center of the vessel is largest.Because of the strain-rate effect

the vessel material′s yield stress is increased 2.2 times.
