V形刻槽预制破片战斗部爆炸仿真研究

Research on Explosion Simulation of V-Shaped Notched Prefabricated Fragment Warhead

利用SOLIDWORKS、ICEM建立预制破片战斗部有限元模型,通过AUTODUN对战斗部爆炸加载及破片飞散过程进行仿真研究,提出了V形刻槽预制破片槽口处有限元划分方法,获得了V形刻槽式预制破片的速度、飞散角等参数;仿真结果与试验结果一致。

The software SOLIDWORKS, ICEM were used to establish the finite element model of the prefabricated fragment warhead. It was simulated that the warhead explosion loading and fragment scattering process by AUTODUN, and a finite element method for notching slots in V-shaped notched prefabricated fragments was proposed. The parameters such as the velocity and scattering angle of the V-shaped notched prefabricated fragments were obtained. The simulation results were in agreement with the experimental results.
