Patent ID: 8306796

Claim:
A method to simulate pyrotechnic shock, comprising: generating a predetermined signal waveform; conditioning the predetermined signal waveform to produce a predetermined shock simulation for a shock test, wherein the conditioning the predetermined signal waveform comprises filtering the signal waveform to select levels of output of the signal waveform across a frequency range of the signal waveform, wherein filtering the signal waveform comprises: filtering the signal waveform with an analog filter to select levels of output at different filter intervals; filtering a filtered signal waveform from the analog filter with a digital filter to control the selected level of shock imparted to the test specimen; amplifying the conditioned predetermined signal waveform to a chosen amplitude to produce a selected level of shock; energizing a field coil and driver coil of a shaker system to produce the selected level of shock; and measuring a shock imparted to a test specimen by the shaker system; and presenting results of the shock test on the test specimen.
