A system (10) for simulating vehicle crashes for testing or evaluating the reliability of a vehicle crash sensor (20) includes a model waveform generator (16) which utilizes a method of modeling an actual vehicle crash waveform to generate an infinite set of model crash waveforms, and subsequently inputs these sets of modeled crash waveforms into a thruster apparatus (12). The thruster apparatus (12) mechanically exerts a force onto the crash sensor (20) corresponding to each input model waveform. The crash sensor response is tracked and analyzed by a test analyzer (18). The model crash waveforms are generated by breaking down a predetermined crash waveform into a crash pulse (signal of interest) and multiplicative noise signal. The multiplicative noise signal is then statistically characterized as a function of time. Randomly variable waveforms from a white noise generator (128) are then modified with the statistical characterization and multiplied with the signal of interest to generate the infinite set of model crash waveforms.
