榴弹攻击下铝质结构抗爆能力的数值评估

Numerical evaluation for resistance-damage ability of aluminum structure under attack of combustion shrapnel

在静爆试验的基础上,结合有限元数值方法对小口径(30 mm)燃烧榴弹舷侧接触爆炸攻击下铝质艇体结构的毁伤进行评估,着重分析了铝质艇体结构在小口径武器攻击下,弹体的攻击角度、弹体的初始侵彻速度以及爆炸产物等对艇体结构破损和毁伤范围的影响以及榴弹爆炸的破片效应.

Based on the explosive experiment results, the FEM is used for numerical evaluation of damage resistance ability of aluminum high speed boat structure under osculant explosion of combustion shrapnel with the caliber of 30 mm. The ship structure damage, the damage range and the second fragments damage are also discussed according to the attack angle, initial-velocity and experiment equations.
