Abstract: 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.

Abstract: A vibration system for a simulator cockpit which includes at least one pilot seat. The vibration system comprises a vibration module for the pilot seat, the seat vibration module being composed of a platform having a top face to which the pilot seat is fixed and a bottom face to which a motor drive system is coupled. The motor drive system comprises independent mechanical means allowing the platform to be made to vibrate on three orthogonal axes, and is coupled to a control module configured to independently actuate each mechanical means and vary, in real time, the amplitude of the vibratory movements of the platform on each orthogonal axis.
