Study of Shock Response Spectrum Control

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.
