A collision test apparatus having input and output members formed from incompressible liquids and between which is positioned a sample whose impact characteristics are to be measured. A compression wave is input to the input member and propagated through the sample and in the output member. Suitable detectors detect the input compression wave, output compression wave and any pan of the input compression wave reflected off the sample.

Collision test apparatus

The invention provides an instrument suitable for measuring seismic waves in an environment which comprises a wave guide through which a seismic wave may propagate substantially without dispersion wherein the wave guide is provided with means for measuring its deformation.

Seismic wave measuring devices

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.
