基于聚能随进破冰器及LS-DYNA数值模拟技术,研究了给定量炸药在水下不同装药深度爆炸时水体表面20 cm厚的冰体的破坏特征,分析了冰面、冰内爆炸与冰下爆炸的结果,可知冰下爆炸的效果要比冰面及冰内爆炸的效果好得多,并将数值模拟结果与现场试验结果进行了对比,验证了数值模拟的可靠性.研究结果对基于聚能随进技术的破冰器材的型号研发系列化有很好的指导意义.
Abstract：Based on LS-DYNA numerical simulation and shaped charge technology,the failure characteristics of 20 cm thick ice when a certain amount of TNT exploded underwater at different depths were studied,and the results of explosion on the surface of ice,in the ice and under the ice were analyzed,which indicated the effect of explosion under the ice was much better than explosion on and in the ice.Then numerical simulation results were compared with experimental results in order to verify the reliability of the numerical simulation.The results may guide the type research of ice-breaking equipments based on shaped charge technology.
