38mm橡皮碰击弹分支展开分析仿真

Process Simulation of 38 mm Rubber Impact Grenade Branch

38mm橡皮碰击弹是通过弹头出膛后的"十字"伸展变形来增大打击面积从而减小弹头终点打击效应的非致命动能弹.为研究弹头出膛后在多大的距离内能顺利完成伸展变形,从而满足其不对人员造成致命伤害的技术要求,利用数值仿真手段对38mm橡皮碰击弹分支展开过程进行了仿真,运用质点弹道模型计算得出了分支展开所需的安全距离,为38mm橡皮碰击弹在实战中顺利应用提供了参考.

38 mm rubber impact grenade is one of the non-lethal kinetic energy projectiles,which reduces the warhead end effects through cross extensional deformation of the warhead after leaving the barrel to increase the impact area. In order to study at what distance the bullet after leaving the muzzle can smoothly complete the extensional deformation and meet the requirements of non-lethal technology, the numerical simulation of 38-mm rubber impact grenade branching extension process has been carried out, the safety distance of branching extension process is calculated by particle trajectory model, and the reference for the 38 mm rubber impact grenades to be applied in actual combat is provided.
