A gravity compensation device solar wing deployment test for low temperature

A method for low-temperature solar wing deployment test gravity compensation device, it is possible to realize solar wings at -120 ° 1/6 gravity and zero gravity cryogenic environment gravity compensation, and the analog months 15 ° to the horizontal surface of the landing limit position completed sun multi-angle flap folding and unfolding the test repeated. The balance lever device uses gravity compensation, all-metal structure to accommodate a low temperature environment; a guide rail and a swing boom complete solar wing three-dimensional trajectory of the center of mass, breaking the bidirectional structure of a conventional solar wing rail and the longitudinal rail transverse rail combination, reduces the complexity of the system, improve the reliability of the deployment movement; freedom with horizontal rotary assembly rotatable in the horizontal plane of the main beam, the gravity compensation break situations is 15 ° to the horizontal solar wings; with block and tackle structure, reducing motion resistance; word using aluminum girder structure, reduce the mass of moving parts, reduce the inertial force when deployed and stowed solar wing movement.
