摘要: 冲击响应谱模拟比规定冲击脉冲来模拟更接近实际冲击环境.采用迭代算法,用指数衰减正弦函数组合出具有规定的冲击响应谱的瞬态冲击加速度波形,其末加速度,末速度和末位移为零满足实际振动台的需要.探讨了瞬态冲击加速度波形实时控制中传递函数的估算和修正方法,以及驱动数据块的大小对控制精度的影响并给出了解决方法.

Abstract: At present, The technique of the control of the shock response spectrum is popular on shock test.The method of sums of exponentially decaying sinusoid components to match acceleration shock response spectrum is described by this paper. The acceleration,velocity,and displacement characteristics of the resulting shock waveforms can meet limitations imposed by the physical capabilities of vibration exciters, And hence The resulting shock waveforms can be reproduced on a shaker using shock vibration control techniques,The principle of reproducing shock waveforms on the shaker is discussed, The estimation and update of transfer function is discussed, The effect of duration of the drive waveform is also analyzed.
