ABSTRACT:
A pyrotechnic shock testing machine employs flexure plates attached to an anvil lying in a vertical plane of a supporting frame to apply pyrotechnic shock pulses to a test unit attached to the anvil when a hammer is dropped to strike the anvil. The dimensions of the flexure plates can be selected to control the lower frequencies of the shock pulse. The anvil materials and their coupling can be selected to control the higher frequencies of the shock pulse whereby shock pulses in the range of 100 to 10000 hertz and accelerations in the range of 50 to 10000 g's can be applied to a test unit in the x, y and z directions. The shock testing apparatus is compact and portable and without the need to have complex hammer raising and dropping mechanisms.
