Gravity compensation device for step-by-step expansion type solar wing ground test

Abstract

The invention provides a gravity compensation device for a step-by-step expansion type solar wing ground test. The device comprises trusses, two sets of transverse guide rails, a plurality of sets ofsliding mechanisms and a swing mechanism. The two sets of transverse guide rails are installed on the upper portions of the trusses through a plurality of truss installation supports, the swing mechanisms are installed on the trusses, the multiple sets of sliding mechanisms cooperate with the two sets of transverse guide rails, and the section of each transverse guide rail is rectangular; each setof sliding mechanism comprises two transverse sliding frames, a longitudinal shaft support and a longitudinal shaft, the upper portions of the transverse sliding frames are erected on the transverseguide rails on the corresponding sides respectively and slide along the transverse guide rails of the transverse sliding frames, the swing mechanism and each longitudinal shaft are provided with a suspension assembly respectively, and the suspension assemblies slide along the longitudinal shafts and the swing mechanism. Therefore, problems that a long guide rail in a traditional large-range two-dimensional unfolding mechanism is difficult to machine, the guide rail machining and adjusting precision requirements are high, and the unfolding process is prone to being jammed are effectively solved, and the device is convenient to carry and has good economical efficiency and applicability.

Description

technical field [0001] The invention belongs to the technical field of solar wing structure and mechanism ground tests, and in particular relates to a gravity compensation device for step-by-step deployment solar wing ground tests. Background technique [0002] In order to simulate the space microgravity environment during the test of the solar wing structure and mechanism products on the ground, it is necessary to compensate the product's own gravity to achieve zero gravity test conditions. Compared with synchronous deployment, step-by-step deployment of solar wings is more complicated and requires a larger deployment space. [0003] At present, there are three commonly used schemes for the gravity compensation device of the solar wing ground test: the air-floor support type, the air-floor suspension type, and the roller suspension type. The air-floating support type needs to be used with a marble platform. The test system is expensive to build and difficult to transport. ...
