Motion system with three degrees of freedom for simulating vertical, pith and wobble motions of motor vehicles

摘要

the motion system has a platform (11) which accommodates the vehicle and three actuators (12) which move the platform which act upon the platform via arms (13) linked to the underside of the platform. The arm application points (14-16) are mutually equally offset about a circular arc (17) and each arm is driven by two synchronised stroke drives (19) which engage the arm at a transverse distance symmetrically about the arm linkage point
