Abstract
Abstract This invention is a motion system for use with simulators, primarily vehicle simulators, which provides random oscillatory motion to simulate the vibration encountered on such vehicles as trains, subway systems, trolley cars, etc. The motion system comprises a fixed base and a movable platform supported on that base at three primary points. Two points laterally spaced from each other support the motion platform on springs and a third support at the other end of the platform comprises a single ball support. Intermediate the pair of spring supports and the single ball support is a motion producing member such as a hydraulic cylinder.
