聚能射流作用下模拟装甲舱室内冲击波试验研究

为研究先进装甲目标内乘员部位冲击波毁伤效应,建立了典型装甲车辆乘员舱室模拟等效目标靶,开展了破甲弹静爆射流穿透装甲钢舱壁及炸药在舱内静爆条件下舱内冲击波试验。试验结果表明:聚能射流穿透装甲舱室后,在舱室内具有一定的冲击波毁伤效应;受射流穿透舱壁时舱体振动、测试位置、壁面反射、传感器安装方式等因素影响,测试波形差异较大;与裸装药在模拟装甲舱内爆炸的试验结果相比,聚能装药爆炸射流穿透舱壁作用下产生的冲击波波形更复杂;若采取无模拟舱底钢板的等效舱试验方法,更加有利于获取有效的超压测试波形。

Experimental Study of Shock Wave in the Simulated Armored Cabin under the Action of Shaped Charge Jet

A simulated equivalent target of passenger compartment of the typical armored personnel carrier is built to investigate the damage effect of shock wave on the advanced armor target.The tests of shock wave in closed cabin were carried out in the conditions of SC static penetration and the static explosion of detonator in cabin.The results indicate that the shaped charge jet can produce a certain damage effect when penetrating the armored cabin;and the test waveforms differ greatly due to cabin vibration,test position,wall reflection and installation methods of sensors when the bulkhead is penetrated by shaped charge jet.Compared with the static explosion of bare charge in cabin,the shock waves produced by shaped charge explosion and jet penetration are more complex,therefore the effective waveform is beneficial to obtain by using the test method of removing the simulated cabin bottom.
