The invention relates to an exciter system for inducing vibrations in railway bridges, which is made up of a servo-hydraulic actuator connected to a railway wagon designed for such purpose so as to be able to transport same over the tracks or else to a (towed or self-propelled) rubber-tyred vehicle. The actuator generates a force by moving a variable-weight reaction mass guided by linear bearings. It comprises hydraulic equipment that enables direct transmission of the vibrations to the infrastructure, independently of the rolling gear of the wagon or the rubber-tyred vehicle, via false wheels. The movement of the actuator piston is controlled by a programmable computer system allowing the actuator to apply general forces on a bridge that do not exceed the maximum acceptable displacement of the piston: harmonic, impulsive, and transient forces. The equipment is provided with the necessary load control elements.
