A device for moving an object comprises a base and a platform able to receive the object; six supports each having an upper end connected to the platform and a lower end connected to the base and an actuation device connected to at least three of the supports. The upper end and lower end of each support in combination have at least five degrees of freedom. The actuation device is suited for giving predefined periodic movements to said at least three of the six supports, these three supports being called controlled supports, thus giving a periodic movement to the platform relative to the base with at least three degrees of freedom.

An apparatus for carrying out load testing on an aircraft part has constraint means for constraining the aircraft part, a linear actuator for applying a test load, having a tiltable first part, pivotally constrained about a first and a second geometrical axes, orthogonal to one another, and a second part, slidably mounted on the first part to slide along a longitudinal direction. A load cell, mounted on the second part, measures a force acting on the aircraft part along the longitudinal direction. A first clinometer and a second clinometer are mounted on the linear actuator. Each clinometer measures a respective angle representative of rotation of the linear actuator respectively about the first and second geometrical axes. A displacement transducer, mounted on the first part, measures sliding of the second part relative to the first part of the linear actuator.

A multi-axis vibration test system uses a mounting fixture formed from a solid block of Aluminum alloy, at least 20″ per side, and machined to form bearing recesses that receive the pad bearings to overcome the problems of existing systems and deliver the required amplitude of linear displacement over the frequency test band in all three, and possibly six, axes simultaneously and uniformly over the mounting surface(s) for both commercial and the more stringent military standards.

The disclosure provides a vehicle excitation advice. The vehicle excitation device that excites a vehicle having a plurality of wheels includes a plurality of excitation machine bodies on which the wheels are placed, respectively. The excitation machine body includes a front shaft and a rear shaft on which the wheels are placed at intervals in the in the front-rear direction of the vehicle, and an actuator (hydraulic actuator) that excites vibration to the wheels by moving at least one of the front shaft and the rear shaft in the front-rear direction. The front shaft is inclined such that the inner end portion of the front shaft in the left-right direction of the vehicle is located closer to the front of the vehicle than the outer end portion of the front shaft in the left-right direction of the vehicle.

The disclosure provides an excitation device, in which a vibration in a front-rear direction generated by excitation actuators is input to second bars via excitation arms and excitation shafts, and four wheels are vibrated by the vibrations of the second bars, so as to rotate a vehicle on at least one of a yaw axis, a pitch axis, and a roll axis. A controller controls a phrase and an amplitude of the operation of each of four piston rods of four excitation actuators.
