test method on impact overload during cluster warhead ejection and scattering

Abstract：In order to accurately measure the shock overload of cluster bomb bullets when the explosive dispersal，a miniature throw tester that can be placed inside the bullets or act as a bullets was designed and functions and features was analysised in this article.Carrying on a further research on the low-power consumption，enhanced treatment and efficient buffer structure.The bullet signal of shock overload in the explosive experiment was successfully obtained after the tester was put in the simulation calibration.In the last，a combining data processing methods which consist of wavelet processing、spectrum analysis and modal analysis was used to analyze the validity and accuracy of the test data.

1.引言

子母弹战斗部是现代高科技战争中常用的一种战斗部，子母弹关键技术之一是抛撒，常用的抛撒方式有活塞抛撒、囊式抛撒、中心爆管抛撒。子母弹抛撒的实质就是把弹头的整体能量变为分散的子弹能量，所以子弹具有很好的分布状态是子弹命中、毁伤目标的决定因素，因此抛撒冲击过载对于子母弹的毁伤效果有着关键的影响。子母弹抛撒过程中，往往要伴随着有高温、高冲击等恶劣环境的影响，对于一个测试系统来说，克服这些困难，对于保证测量的可行性，准确性尤为重要。针对种种问题，本文介绍了一种基于存储测试技术的弹载测试仪。这种弹载测试仪可以置于子母弹的子弹中，可以实时、准确、完整的记录下爆炸瞬间子弹受到的冲击过载。文中就这种弹载测试仪进行了详细的介绍，并就成功运用在某型号战斗部模拟子母弹中心管爆炸抛撒的测试实验中得到的测试曲线进行了处理，并获取了满意的测试结果。
