摘　　要：弹药在动态加载下破片威力必然发生变化,静爆试验方法已经不再适用。为获取弹药动态加载下破片分布威力场,设计一种炮射弹药的动态加载试验,通过高速摄像和标杆获取弹药的动态炸点。预设碰撞触发靶,设置同步触发,同步高速摄像和电测系统,获取弹药动态加载爆炸后破片的飞行时间。建立动态炸点与矩形破片拦截靶和测速靶的对应关系,结合静爆破片威力场处理方法,获取弹药动态加载下破片的轴向分布、破片的动态飞散角和动态飞散方位角以及破片的平均速度,试验结果可为实弹条件下弹药威力和毁伤评估提供技术支持。Compared with the static blast test of ammunition,the dynamic damage field of fragments will change definitely.In order to obtain the power field of fragments from a moving bomb,a dynamic loading test of gun-launched method was designed.The dynamic detonation point is determined by high-speed camera and the benchmark.Preset collision trigger target,set up synchronous trigger,synchronize high-speed camera and electrical measurement system,then the fragment flight time can be obtained.Combined with the data processing method of static test,the relationship between dynamic detonation point,the rectangular fragment interception target and fragment velocity is established to obtain the axial distribution of fragments,the dynamic dispersal azimuth angle and the average velocity of fragments.The test results can be used for evaluation of ammunition power under actual combat scene.
