摘　　要：因为传递介质的不同,装药水下接触爆炸载荷输出与空气中存在较大的差异。而由于水下接触爆炸破坏程度高及水中测试难度大等因素,装药水下接触爆炸驱动能力的试验测量一直处于停滞状态。该文基于空气猛度摆的原理设计用于测量水下接触爆炸驱动能力的弹道摆,装置主要通过测量炸药水中爆炸作用下摆锤的摆角获取炸药对接触刚性表面的冲量,从而得到表征装药水下爆炸冲击波及爆轰产物的驱动能力。通过对装置多阶段的整体及局部设计,建立猛度弹道摆试验方法,获得炸药端面冲量输出特性,为水下接触爆炸载荷定量分析提供技术支撑。Because of the difference of transmission medium,the load output of underwater contact explosion of charge is quite different from that of air.Because of the high damage degree of underwater contact explosion and the difficulty of underwater test,the test measurement of the driving ability of underwater contact explosion of charge has been in a stagnant state.In this paper,a ballistic pendulum is designed to measure the driving ability of underwater contact explosion based on the principle of air-force pendulum.The pendulum angle of the pendulum under underwater explosion is measured to obtain the impulse of the explosive on the contact rigid surface,and the driving ability of the shock wave and the detonation product of underwater explosion is obtained.Through multi-stage overall and local design of the device,the test method of the violent ballistic pendulum is established,and the impulse output characteristics of the end face of the explosive are obtained.This measurement technology provides technical support for quantitative analysis of underwater contact explosion load.
