| 摘 要： | 为了研究近地面化学爆炸的冲击波传播特性,在试验场进行了不同当量的TNT近地面爆炸试验,并应用有限元方法模拟了其中2种工况的冲击波传播过程。数值模拟结果与试验数据吻合较好,表明计算模型和参数选取的合理性和正确性,该模型和算法可以为进一步研究近地面爆炸冲击波传播特性提供有效手段。

| Abstract: | For study of the propagation of shock wave by chemical explosion on the ground,the different amount TNT was experimented at testing ground.The finite element method was also used to simulate the two cases.The results show that the simulation results agree well with the test results,and the finite element model and algorithm presented in the paper are beneficial to the further study of propagation of shock wave by explosion on the ground.. |
