Abstract
A rotational shock/vibration fixture that adapts a rectilinear shock or vibration apparatus for applying a rotary shock or vibration 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. 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. A reduced backlash linkage between the box to the rectilinear shock or vibration apparatus couples rectilinear movement of the shock or vibration apparatus into rotary shock or vibration of the box. The reduced-backlash linkage may include a lever arm for mechanically amplifying shock applied by the shock or vibration apparatus.
