Disclosed is an immersive multimodal ride simulator comprising a virtual reality unit for delivering audio-visual simulation of a ride experience to a user, a motion unit for delivering motion simulation of the ride experience to the user wherein, the motion unit comprises a user cockpit, the exterior of which being at least partially rounded, the cockpit comprising an extension member extending therefrom, and a cradle comprising a plurality of omnidirectional load-bearing units. The cradle receives the cockpit such that, the conveyor units permit the 3D rotational movement of the cockpit. The simulator further comprises an actuation assembly for imparting rotational motion to the extension member resulting in the cockpit being subjected to three-dimensional rotation and imparting vertical motion to provide vertical movement. A controller assembly enables the user to interact simultaneously with the audio-visual simulation and motion simulation actuators without having to directly interface to the motion simulation software.

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.

A device that makes it possible to make the movements of moving platforms safer and relates more particularly to a linear actuator that can be used in a hexapod positioner supporting a load is provided. The actuator is actuated by electric control and comprises at least one hydraulic damper positioned on the actuator such that the forces generated by damping in the event of extreme breakdown are experienced only by the load and are distributed such as to limit force and acceleration peaks.

A vehicle nonlinear dynamics simulation device, such as flight simulator, including a motorized spherical vehicle suspended inside another spherical shell which has smooth inner surface. The spherical vehicle is supported by a plurality of spiky legs of either air-bearing assemblies or omni-directional ball bearing assemblies. The outer spherical shell is supported by three controllable translational motion platforms. Simulating equipment for a pilot cabin is mounted inside the spherical vehicle. The spherical vehicle has driving, restoring, and damping capabilities in roll, pitch, and yaw directions and is capable to rotate 360 in any directions. Therefore it provides a dynamically equivalent model to simulate a vehicle rotational dynamics. The driving and restoring means include Omni wheel assemblies mounted outside of the spherical vehicle and operable to contact the inner surface of the shell to drive the spherical vehicle in roll, pitch, and yaw directions. The driving means include electrical motors. The restoring and damping mechanisms are provided by rotational springs and rotational dampers, respectively. The rotational movements of the spherical vehicle are active and controlled by the driving system and also by the nonlinear dynamics of the spherical vehicle itself, in contrast to the passive movements of the simulation platforms currently used in industries.
