Numerical Simulation of Blast Destroy Speciality in Ammunition Cavity Ware House

Cai Junfeng1,Yi Jianzheng1,Liu Guoqing1,Xie Changhong2 (1.Ordnance Engineering College,Shijiazhuang 050003,China;2.,Units 78465(PLA),Guangyuan,Sichuan 628000,China)  
It is possible that the earth penetrator detonates in ammunition cavity warehouse along with the development of the precision guidance ammunition.The defense ability of underground project is facing bigger and bigger challenge.A finite element model is founded according to the data of some ammunition cavity warehouses.The blast destroy characteristiss in ammunition cavity warehouse is simulated on AUTODYN by ways of Euler-ECT and flow-solid coupling.The characteristics of blast wave spread and peak pressure in ammunition cavity warehouse and damnification of the ammunition are analyzed.The numerical simulation result forms the base for destroy evaluation and defend of blast in ammunition cavity warehouse.
