射弹破片三维空间飞散矢量模型

A Three-Dimensional Scattering Vector Model of Shell Fragments

针对破片毁伤的关键环节,对破片飞散规律进行研究。根据实弹射击试验,得到榴弹破片飞散分布规律,建立榴弹破片飞散假设,以此建立榴弹破片飞散场模型;依据单个破片飞散经纬角和炮弹落角,建立单个破片静态飞散矢量模型和动态飞散模型,并以152 mm伤爆弹对目标进行毁伤模拟。实验结果表明:该模型数据在毁伤目标概率50%以上时,与实际实弹试验数据情况基本吻合。

Aiming at the key parts of fragment damages, studies the scattering rules of fragments. Based on artillery firing experiments, it finds out the scattering rules of shell fragments, from which it establishes a hypothesis of scattering fragments to construct the model of the fragment scattering field. It establishes the static and dynamic scattering vector models of a single fragment by the scattering angle of longitude and latitude and the angle of fall of shell. It carries on the simulation of targets damage by 152 mm shell. The results are very close to the ones from firing experiment when the probability of targets damage is over 50%.
