引信冲击试验随机驱动信号的生成方法

The Method for Generating the Driving Signals of the Fuze Shock Tests

文中阐述了一种生成冲击试验驱动信号的方法。该方法通过对实测冲击信号(这里是指作用于引信部位的冲击加速度信号)的傅立叶谱进行统计分析,结合随机数的产生法,生成了满足时域特性的随机冲击信号。为仿真引信虚拟样机模型在冲击环境下的动态特性分析提供可靠的数据支持。

A method is set forth in this paper for generating the driving signals of the fuze shock tests.By analyzing sta- tistically the Fourier spectrum of shock signals acquired from shock tests and combining with the generation method of random data.the random driving signals can be obtained.The data can be used as input signals for dynamic characteris- tics analysis of fuzc virtual prototype.
