Abstract
Two impact energy attenuators operating on the principle of cyclic straining of materials were tested to determine: (1) maximum output accelerations and (2) resultant attenuator deflections. The attenuators were tested in tension with initial impact velocities from 914 to 1338 centimeters per second and maximum input accelerations from 21 G to 58 G. The attenuators were tested in compression with initial impact velocities from 546 to 855 centimeters per second. The maximum output acceleration showed dependency upon payload that was consistent with the attenuator design theory.
