基于AUTODYN的明胶靶弹道仿真研究

Simulation of bullet trajectory in gelatin target based on AUTODYN

为更好地揭示步枪弹与明胶的相互作用过程及作用机理,采用AUTODYN软件对贯彻过程进行了仿真,并通过试验验证了模型的准确性。对不同方案弹头在明胶中的速度、加速度和贯彻深度进行了分析。结果表明,弹头加速度增大,破碎时间会提前;合理结构会减小碎片贯彻深度。

In order to better reveal the interaction process and mechanism between rifle and gelatin, the implementation process was simulated by AUTODYN, and the accuracy of the model was verified by ex periments. The velocity, acceleration and implementation depth of different projectile in gelatin were ana lyzed. The results show that with increasing acceleration of bullet, breakdown time will be advanced. Rea sonable structure will reduce the depth of debris implementation.
