Initial discoveries involving the affect of impact velocity and impact angle on penetration acceleration are obtained. Simulations of AUTODYN-3D hydrocode show that impact velocity and impact angle affect the penetration acceleration significantly. Penetration acceleration increases as impact velocity increases; however it appears a contrary trend as impact angle increases. The witness experiments of 56mm diameter projectile with different impact velocities penetrating 603-typed armor show a quite good agreement with the simulations, and penetration acceleration increases as impact velocity increases, and the maximum acceleration appears in the time range of 0.05—0.2ms., authors=YU Qingbo, WANG Haifu, YU Weiming, authorsList=YU Qingbo;WANG Haifu;YU Weiming,

articleAbstract=数值模拟和实验研究动能弹侵彻装甲靶板作用行为,初步获得了着速、着角对过载的影响规律。AUTODYN-3D数值模拟结果表明,着速、着角对侵彻过载影响明显,侵彻过载峰值随着速的增加而增大,随着着角增大而减小,但变化趋势有所缓和。针对不同速度正侵彻问题进行了实验验证,数值模拟结果与实验结果较为吻合,结果均表明,随着速度的增加,过载呈现出明显增大的趋势,且最大过载出现时间为0.05—0.2ms范围内。,
