Pagination or Media Count:
Copper-ball accelerometer operation and utility as a shock spectrum measuring device are discussed. The results of dynamic and static tests of copper balls are recorded. A comparison is made of the dynamic and static properties of copper balls. In order to arrive at a more accurate calibration of copper-ball accelerometers, correction is made for the non-linear deformation characteristics of the copper balls. Corrected accelerometer functions are presented in easy-to-use curves and nomographs for velocity change, peak g, and associated natural frequency.
