摘　　要：为了分析水压爆破式破门弹对防弹安全门的破拆效果,运用有限元软件ANSYS/LS—DYNA建立了普通耦合爆破方式和水压爆破方式破门弹的有限元分析模型,采用ALE方法对2种不同的爆破方式进行流固耦合数值模拟,对其爆破后空气压力时程和防盗安全门钢板的位移进行了对比。仿真结果和实爆试验表明:在相同的装药量情况下,水压爆破式破门弹不仅具有破拆速度快、防盗安全门变形大等特点,而且产生的空气冲击波和噪声强度小、粉尘少、碎片飞散距离小。该结论为破门弹装药量和装水量的确定提供了理论依据。In order to analyze the forcible entry effect of dynamic entrance tool on burglary resistant safe door by water pressure blasting,the finite element models of dynamic entrance tools based on coupling blasting and water pressure blasting were built by the ANSYS/LS-DYNA.The air pressure and the steel deformation in two different methods were obtained by ALE algorithm.The simulating and experiment results illustrated that the forcible entry speed and deformation of the dynamic entrance tool from water pressure blasting was larger than the coupling blasting,and also reduces the noise,dust,the flying distance of the debris.The conclusion provides the foundation for the charge and quantity of water in the design of dynamic entrance tool by water pressure blasting.
