A vehicle simulator having a pilot's cabin, a screen, and a moving system, which is suited to move the pilot's cabin in the space. The moving system has a fixed base arranged horizontally, a mobile platform which supports the pilot's cabin and rests on the fixed base so as to freely slide on the fixed base itself, and at least one actuator device, which is mechanically connected to the mobile platform. The actuator device has at least one flexible thread-like element which is mechanically connected to the mobile platform, and a motorized mechanism, which is suited to apply a pulling force to the flexible thread-like element, so as to always keep the flexible thread-like element in tension and, when needed, pull the mobile platform towards an edge of the fixed base.
