摘要： The invention is directed to a movement simulator (1) comprising of a moveable support (2) having three translational degrees of freedom connected to a base (3) by means of three actuators (4), wherein each actuator (4) comprises a rotating shaft (5) having two outer ends (6,7) and comprising two spaced apart cranks (10,11), an electric motor (21) comprising a rotor (22) and a stator (23), a support structure (8,9) comprising bearings (26,27) for the rotating shaft (5). The support structure is connected to the base (3), a pair of links (12,13) connecting the cranks (10,11) of shaft (5) to the moveable support (2). One crank (10) is positioned at one outer end (6) of the shaft (5) and the other crank (11) is positioned at the opposite outer end (7) of the shaft (5). Part of the rotating shaft (5) is the rotor (22) of the electric motor (21).

摘要： The invention is directed to an overdetermined movement platform system, comprising a base; a platform movable along 6 degrees of freedom relative to said base; at least eight long-stroke actuators, wherein each actuator couples the base with the platform and a controller which (a) is configured to adapt a demanded platform movement set-point to a commanded platform movement set-point, (b) is configured to move the eight long-stroke actuators such that the commanded platform movement set-point is achieved and (c) is configured to dynamically redistribute the forces as exercised by the actuators on the platform between the actuators.

摘要： A motion platform system comprising a motion platform which is supported above a base by displacement units. Displacement units comprise a drive unit which drives a crank. A connecting arm is connected between the crank and the motion platform, so that translational and tilting movement of the motion platform is achieved by appropriate operation of the drive units. Each connecting arm has a curved profile which enables a full range of movement of the motion platform to be achieved using connecting arms of relatively short length. The connection between the connecting arm and the crank arm can be brought close to, or within, the crank arm. The height of the motion platform above the base, and bearing loads within the drive units, can thus be reduced.
