摘　　要：该文用计算机仿真的方法 ,进行了用电动振动台实现模拟爆炸冲击环境的冲击响应谱控制方法研究 ,根据冲击试验规范合成时域波形 ,分量级转化为驱动信号输入到振动台系统 ,计算系统响应加速度及冲击响应谱 ,用波形幅值均衡法对冲击响应谱进行修正 。Using computer simulation to study SRS control method while using electrodynamic shaker to simulate pyrotechnic environment. A time-history waveform is synthesized according to the shock test specification. Several low level drive signals are outputted to shaker system. The acceleration response and its SRS of shaker system are calculated. Applying the waveform amplitude equalization method to modify the SRS and achieve SRS' control.
