Abstract: A hexapod actuator device, notably used in flight simulators or driving simulators, includes six legs. A first end of each leg is notably mobilizable along a straight segment by virtue of a motorized carriage. The hexapod actuator comprises notably six segments of straight lines that may be coplanar or inclined with respect to the ground. A second end of each leg may be mounted free on a ball joint with three degrees of freedom in rotation. Each of the ball joints is secured to a mobile platform. The device lies in the field of systems allowing motion to be imparted to pilot cabins for example.

Abstract: The disclosed motion device comprises a triangular platform supporting a load, for example a simulator cabin. This platform is supported at all three corners by hinged arms driven by cranks that are moved by an actuator. There is provided a load compensation device facilitating the work of the actuators. Thus the load can be moved in pitch and roll as well as vertically.

Abstract: A motion simulator for vehicle driver training, which includes at least three actuators placed at the vertices of a triangle, connected to at least three connecting points, arranged in a triangle, for the fastening of a platform of a cabin by lever arms, one end of each of these arms being connected to a corresponding actuator by a joint with two degrees of freedom, the other end of one of the lever arms being connected to a point for fastening the platform by the joint with two degrees of freedom, and the other end of the other lever arms being connected, at all times, to one of the other platform fastening points by a joint with at least four degrees of freedom.

Abstract: A relief sensor for a vehicle motion simulator of the type mounted on a carriage moving over a gantry above a relief model of the piece of ground. The skid of the relief sensor, which is in contact with the model, comprises relief portions at positions corresponding to the positions of the endmost wheels or track carrying rollers of the simulated vehicle.

Abstract: A member placed in a vehicle driving simulator makes it possible to simulate the hydraulic braking and driving controls. It comprises a cylindrical envelope in which slide a first member and a piston joined by a tubular elastomer spring, whose compression simulates the deformation of the hydraulic pipes and the braking members. With the bottom of the envelope, the piston forms a back-pressure chamber which is supplied with compressed air and makes it possible to simulate the feedback of the braking system. A retractable stop at the bottom of the envelope and on which bears a rod extending the piston, makes it possible when it is retracted, to simulate a hydraulic circuit failure.
