Abstract
A mechanism is provided for oscillating a shake table or other member at high accelerations but over short distances. The mechanism includes a group of pad devices supporting the shake table on a base, with each pad device including upper and lower curved pads respectively received in sockets of the table and base and with the pads able to slide on one another. However, the centers of curvature of the two pads are spaced from one another, so that when a driver rotates the lower pad in its socket, causing the upper pad to rotate in its corresponding socket and slide on the lower pad, the upper pad is displaced vertically by a slight amount. Thus, an actuating device that applies a moderate force to the lower pad to rotate it, therefor applies a much greater vertical force to the table, to accelerate it at a high level. The pad devices also can support a large static loading on the table as where it lies in a centrifuge.
