Systems approach to measuring short-duration acceleration transients
Abstract
A shock measurement system was developed in which the quartz seismic system, two poole active filter and an FET source follower are incorporated in a transducer housing. It is shown that the system will survive + or 100,000g without damage. The PCB can supply different ranges as required. The PCB Model 305M23, can obtain data comparable to those of standard piezoelectric and piezoresistive accelerometers when high frequencies are absent. In the presence of high frequency stimuli, the accelerometer has obtained data without over ranging its data channel and without introducing error signals from excitation of the resonant frequency of its seismic system. It is useful for impact and pyrotechnic measurements. The development effort and test program have enhanced the probability of acquiring successful structural measurements in harsh mechanical loading environments.
