弹体撞击水幕动态响应试验方法研究
|
摘要
设计并建立了一套弹体撞击水幕试验系统,模拟了弹体高速穿透空间密度分布不均流体介质的过程。通过试验,获得了弹体自身在撞击水幕过程中的冲击过载曲线以及弹道变化图像,该试验原理、装置以及试验方法为分析雨水、人造水幕等特殊毁伤元素对炮弹、导弹等弹体的毁伤作用提供了参考。
An experimental system was designed and set up for projectile impacting water curtain. The process that projectile pierced through the fluid medium which have the uneven density in the constant space was simulated. The g curve and trajectory have obtained when the projectile impacting the water curve. The test principle,equipment and method can provide an important experience and reference for the analysis and research on the damage effectiveness of the rain and artificial water curtain to missile and artillery shells.
