摘要为了处理人群密集区域的危险品弹药，设计了一种爆炸式水刀装置。使用聚能装药的相关原理，以线性切割器为模型，研究了射流成型与射流侵彻的相关理论，并建立了工程模型。以建立的工程模型为研究对象，运用AUTODYN动力学软件进行仿真，通过对仿真结果的分析对工程模型进行改进，最终得到了一套能够满足使用要求的爆炸式水刀装置的设计方案。60102

通过和金属切割器的仿真模型进行对比， 40mm直径的水刀装置能够在不引爆钢板后部炸药的同时切透16mm的钢板，而40mm直径金属切割器虽然能够切透钢板，但同时也会引起炸药爆炸。60102

Title  Scheme Design of Explosive Water Jet Device Destroy   Dangerous Ammo                                                   

Abstract To handle hazardous crowded area of dangerous ammo, explosive water jet device is designed. Based on the relevant principles of shaped charge, in a linear shaped charge for a model, water jet formation and penetration process was studied and engineering model was established. By dynamic software AUTODYN, the engineering model established before was done for numerical simulation. Through the analysis of simulation results to improve the engineering model, got a set of meet the requirements of the explosive water knife device design scheme.

Through the comparison between the simulation model and metal cutter, 40 mm diameter water jet device can cut through the 16 mm steel plate at the same time don't cause the charge exploding at the back of steel plate. Although 40 mm diameter metal cutter can through the 16 mm steel plate, but the same time, the charge at the back of steel plate was exploded.
