ABSTRACT:
A rotational shock fixture, energized by an impulsive driver, applies a rotary shock to a device undergoing test. A rotatable device-mounting-plate, enclosed within a rigid box, receives the device. A pair of diametrically opposed bearings support the box within a frame for movement about a rotation axis. A brake, coupled to the rotatable device-mounting-plate abruptly stops the rotatable device-mounting-plate from whirling about the rotation axis thereby applying the rotary shock to the device. Optional coil springs, stretching between the box and the frame, establish a rest orientation for the box with respect to the frame, and dampens oscillations of the box.
