Research on the time-history waveform synthesis of shock response spectrum

为利用电动振动台进行模拟冲击环境试验给出了一种时域冲击波形合成方法。依据冲击响应谱时域合成的一般原则,选择合成小渡中的正弦窗波作为基本波形,给出了确定各基本波形的波形参数的方法。计算结果表明本文所提算法是有效的,所合成的时域冲击波形能够满足参考冲击响应谱的精度要求,为开发冲击谱试验的控制软件研究者提供了一种思路。

Present an effective shock response spectrum （SRS） time-history waveform synthesis method for simulating shock environment with electro -dynamic shakers. Give out the method to get the parameters for each basic waveform by chosen the Sine Window Function Waveform which is one type of the synthesis waveforms as the basic waveform ,and based on the SRS time-history synthesis principle, The algorithm used to generate the time -history shock waveform could satisfy SRS accuracy requirement, and can be a reference for the researchers who develop the control software for the SRS test.
