Abstract
A compression wave or pulse generation apparatus and method are capable of generating a compression wave or pulse in a vehicle or large structure under test, and include an impactor bar or member held during use adjacent one end of the vehicle or large structure under test and supported to resist movement in a direction away from the large vehicle or structure. The impactor bar is preloaded in the direction away from the vehicle by a hydraulic or pneumatic actuator. In use, the preload force can be quelled suddenly, for example, by triggering an explosive bolt in the impactor bar, so that the impactor bar is released into impact or energy transfer with the vehicle or large structure under test to transmit a compression wave or pulse through the vehicle or structure. Energy flow transducers in the form of elongated bar members are selectively arranged to measure the mechanical energy propagated along the vehicle or structure subjected to the stress wave under simulated crash conditions.
