STUDY ON ERROR SOURCE AND APPLICABLE CONDITONS OF VELOCITY STEP TECHNIQUE FOR ESFIMATING SHOCK RESPONSE AMPLITUDE

Shan Shujun,He Lin(Institute of Noise & Vibration,Naval University of Engineering,Wuhan 430033)  
Shock motion is often simplified as a step function of velocity versus time when its acting duration of a shock is far smaller than the natural period of a shock isolation system.This technique makes analysis and calculation of shock response easier.So it is broadly used in estimation of shock response amplitude and shock spectrum.But its old applicable conditions are not sufficient actually when this technique is used in a damped shock isolation system.So it is(abused) for a long time.Study on its error source and applicable conditions is put forwarded here.
