  • Pyrotechnic shock simulation system and method
    Patent number: 8306796
    Abstract: A system to simulate pyrotechnic shock may include a pulse or signal generator to generate a predetermined signal waveform. A signal conditioning device may be included to condition the predetermined signal waveform to produce a predetermined shock simulation for a shock test. The system may also include a power amplifier to amplify the conditioned predetermined signal waveform to a chosen amplitude to produce a selected level of shock. A shaker system produces the selected level of shock in response to an amplified signal waveform from the power amplifier. A shock measuring device measures a shock imparted to the test specimen, and an output device presents a result of the shock test on the test specimen.
