Abstract: A plurality of eccentric rotors are rotatably fitted between a fixed base and an output shaft on which an object to be vibrationproofed is mounted, the output shaft being supported movably in 3 to 6 Degree-of-Freedom, magnet spring mechanisms are provided on fitted wall surfaces between the fixed base and the eccentric rotor, a composite vibrationproof adjusting spring is provided between the fixed base and the output shaft, the magnet spring mechanism responding to a fine displacement of the output shaft, and in a case where the output shaft is greatly displaced, the output shaft is braked so as to be restored to a predetermined position by the composite vibrationproof adjusting spring mechanism. The magnet spring mechanism produces a large braking force since a rotational angle is large and a rotational-angle speed is high due to eccentricity of eccentric rotors.

Abstract: A docking and active damping device for space structures is provided, in a docking portion of one space structure to be docked, with a positioning device in which an output rotor can be moved and rotated within a two-dimensional plane by a composite rotation of one or more eccentric rotors capable of being independently driven and controlled by a direct drive motor and the output rotor, and a docking member having a docking ring and a latch mechanism are supported on the output rotor of the positioning device. A probe having a capture device capable of being protruded and driven in an axial direction by a linear motion is provided inwardly of the docking member, and the probe provides a 4-freedom movement according to a position of the passive side to capture and dock a drogue.
