摘要

应用ANSYS/LS-DYNA有限元软件对三种防爆罐在1.2kgTNT爆炸载荷作用下的动态响应过程进行数值模拟。研究了无夹层、聚脲弹性体夹层和橡胶夹层防爆罐的抗爆性能。分析了不同夹层对防爆罐整体变形的影响，并分析了聚脲弹性体和橡胶夹层的吸能特性。通过聚脲弹性体夹层防爆罐在爆炸载荷作用下的变形试验研究，验证了数值计算结论的可靠性。结果表明，在相同爆炸载荷作用下，无论是在变形还是在能量吸收方面，聚脲弹性体夹层防爆罐都要优于无夹层防爆罐和橡胶夹层防爆罐；冲击波在聚脲弹性体传播过程中衰减幅度最大。

Abstract

The finite element code ANSYS/LS-DYNA was used to numerically simulate the process of dynamic response of three kinds of explosion-proof pots under explosive loading of 1.2 kg TNT. Antidetonation property of explosion-proof pots made of different sandwich structure with no-sandwich, polyurea elastomer and rubber was studied. The effects of different sandwich structure for global deformation of explosion-proof pot and energy absorption characteristic of polyurea elastomer sandwich and rubber sandwich were analyzed. The reliability of the simulation results was validated by deformation experiment of explosion-proof pots made of polyurea elastomer sandwich under explosive loading. The results demonstrated that explosion-proof pot made of sandwich structure with polyurea elastomer is superior to the ones without sandwich and made of rubber sandwich under the same explosive loading, either in deformation or in energy absorption. Attenuating range of shock wave propagation in polyurea elastomer is the largest.
