ABSTRACT:
In order to give a relatively large number of people, for example twenty-five to sixty people, the sensation of experiencing an earthquake, without those people running any risk, an earthquake simulator for a theme park comprises a platform 1 on which at least twenty-five chairs 5 provided with safety straps or seat belts are fixed, an underframe 4, and at least three hydraulic cylinders 2, 3 which are fixed between fastening eyes of the underframe and of the platform by means of ball bearings or universal joints, in such a way that the platform can move with at least three independently driven degrees of freedom. Said cylinders form part of a hydraulic circuit whose valves can be controlled by a programmed microprocessor.
