Systems approach to measuring short-duration acceleration transients
A shock measurement system has been developed in which the quartz seismic system, two-poole active filter and an FET source follower are incorporated in a transducer housing measuring 5/16'' hex.x 5/8''. Tests have shown that the system will survive +- 100,000g without damage. Although the results reported here are for accelerometers ranged to +- 20,000g, there is no reason to limit the accelerometers to that range and PCB can supply different ranges as required. The PCB Model 305M23, developed to Sandia's specifications, has proved capable of obtaining data comparable to that 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 should, therefore, be especially useful for impact and pyrotechnic measurements. These shock accelerometers are in the process of being fielded in earth penetrator vehicles; in shale rubblization experiments will soon be available. It appears this joint development effort and test program has greatly enhanced the probability of acquiring successful structural measurements in harsh mechanical loading environments.
