爆炸冲击下某型装甲车内PBX装药的力学响应
Mechanical Response of PBX Charge in a Type of Armored Vehicle by Explosive Impact
摘要
Abstract
There are bounce phenomenon of vehicle mounted ammunitions caused by explosion impact,therefore it is urgent to find out the movement trend of vehicle mounted ammunitions and the mechanical response of the charge.In order to analyze the movement trend of vehicle mounted ammunitions and the mechanical response of the charge under different sources of damage,a typical damage source fluid-solid coupling simulation model was built,and the damage to a type of armored vehicle loaded with ammuni-tions was simulated.The results show that,in the case of approximately equal damage source charge ratios,the greater the length-diameter ratio of the damage source,the greater the degree of deformation of the armored vehicle's base plate,and the impact load exerted on the munition by the deformation of the base plate is the direct cause of the munition's bounce,the movement trend of vehicle mounted ammu-nitions is slope-like.When the damage sources are different,the small deformation of the bottom plate of the armored vehicle can still impose a large impact load on the vehicle mounted ammunitions.The neck position and the bottom position of the ammunitions are subjected to a large amount of pressure,and these locations should be considered as priority protection areas.This study can provide a reference basis for the transportation and protection of energetic materials.关键词
