不同介质侵彻过载特征参量有限元仿真方法
Simulation Method of Overload Characteristic Parameters for Different Medium Penetration
【摘要】 针对硬目标侵彻的目标结构日益复杂化而通过深度计算不能控制弹丸在特定介质层爆破的问题,进行了混凝土和钢板介质的过载仿真分析。在仿真过程中提取了侵彻过载曲线的四个特征参量,利用这些特征参量来了解不同介质过载曲线的差异。经实弹靶试证明,通过提取的特征参量可以较好地掌握侵彻过载变化情况,为基于不同介质的侵彻炸点控制提供了支持。
【Abstract】 Aiming at the problem of low capacity for controling bomb exploding in the appointed mudius,the process of penetrating steel plate and concretes is numrerically simulated.The typical modulus of deceleration-time curves are obtainde during the penetrating,and the differents between deceleration-time curves can be realized through the modulus.The live firing experiment proves that,these modulus can help realize the process of penetration,and lays foundation for the point exploding control based on different mediums.
