摘要
为了研究弹药侵彻过程中的火工品受力环境,通过文献和实弹试验结果,分析了弹药侵彻单层混凝土目标时火工品承受的过载加速度值、过载持续时间和过载波形特性。37-100mm口径弹药以300-450m/s侵彻目标时,加速度峰值在15 000g-50 000g,过载持续时间集中在4-5ms。侵彻混凝土和钢筋混凝土(2%钢筋率)目标时过载特性和过载值基本相同。火工品在弹药侵彻过程中将承受交替的压缩和拉伸的应力波作用,同时也承受低频减速过载作用。
Acceleration, loading time and profde characteristics of acceleration woe analyzed to research shock environment of initiating explosive device in the process of projectile penetrating into concrete. Results showed that aceelerafion peak and loading time are 15 000g-50 000g and 4-5ms respectively in 37-100mm cargo projectiles with 300-450m/s penetrating velocity. The acceleration characteristics and strength of penetration are similar between concrete and armored concrete. Initialing explosive device will endure high frequency stress wave induced by structure of projectile and low frequency deceleration.
