摘要
为了从理论上得到给定初始条件下可变形战斗部的弹体变形型面,将战斗部变形部分的结构简化为辅助装药对单层圆柱壳体作用的结构,将圆柱壳体作为理想刚塑性材料,建立圆柱壳体的五塑性铰位移模式,应用刚塑性动力学原理,得到战斗部弹体变形型面的理论模型,模型计算结果与实验结果吻合较好。
In order to forecast theoretically the deformation shape of a deformable directional warhead on the given initial conditions, the structure of the deformable directional warhead on deforming phase was simplified as the single-layer cylindrical shell with a deforming charge, and the cylindrical shell was regarded as rigid-perfectly plastic material. A model for analyzing the deformation shape of the deformable directional warhead was established by using the five-plastic-hinge displacement mode of the cylindrical shell and the principle of rigid-perfectly plastic. The theoretical results by this model a- gree well with the experimental results.
