PELE弹侵彻过程壳体膨胀破裂的数值模拟

Numerical simulation of penetration process for PELE projectile against target

采用AUTODYN-3D和基于Mott破片分布理论的Stochastic随机破碎模型对横向增强效应弹丸(PELE)侵彻过程钢壳体膨胀过程进行了三维数值模拟,对比分析了旋转和着角两因素对弹丸侵彻铝靶时壳体破裂产生自然破片的影响,得到了破片数量质量分布及径向速度梯度等变化规律。

Using AUTODYN-3D Code and Stochastic model to simulate natural fragmentation of PELE impact aluminum target based on Mott distribution. Numerical simulation result of PELE penetration with rotation and impact angle are analyzed, then statistics of fragments number-quality distribution, gauge the azimuth angle and range of lateral velocities are represented.
