A mechanical stop for a moving body that minimizes bounce of the moving body after the body has hit the stop. The mechanical stop includes a flat plate having a plurality of generally triangular sectors defined by radial slits. The slits or triangular sectors prevent excessively large diaphragm stresses in the material of the plate and also reflect the flexural waves in the plate in such a way that the waves have difficulty returning to the contact area where the moving body has hit the stop and are maximally dissipated by internal friction of the plate. The mechanical stop may include a lever between the moving body and the flat plate to change the effective mass of the moving body, a spring to mediate the impact of the moving body, a relatively rigid support for the lever to minimize moments produced in a base for the flat plate, and straight line plate supports for some or all of the sectors of the flat plate to provide desirable reflections for the flexural waves in the plate.
