Zero deformation framework device for satellite load test
2009
The invention relates to a ground test unit for a satellite effective load, and discloses a zero deformation framework device for a satellite load test. The device comprises a combined device [1], and two sides of the combined device are provided with four hanger shaft devices [2]; the front and two sides of the combined device are respectively provided with support devices [3] for mounting a hinge unfolding mechanism, a support [4] of an effective load unlocking release device and a support [5] of a support locking mechanism; the middle of the front of the combined device [1] is provided with a platform device [6] connecting a satellite structure and an antenna array; the bottom of the combined device is provided with two leg devices [7] and a bottom plate [10]; and two hanging rods [8] are fixed on the bottom plate [10]. The zero deformation framework device solves the problems that an expansion coefficient of the test unit is larger, a test result of a product is influenced and the like in the prior art, and has the advantages of simple structure, convenience of installation, good expandability, high adaptability, low manufacturing cost and the like.
