Zero-gravity suspension type deployment test device

The invention relates to a solar cell array and antenna deployment test device for spacecraft such as a satellite and the like, and provides a zero-gravity suspension type deployment test device which overcomes the shortcomings of the air-floating deployment test device in the prior art and solves the problem existing in simulation of the zero-gravity state of the environment orbit of the solar cell array and antenna of the satellite in the ground gravity environment. The zero-gravity suspension type deployment test device is characterized by comprising a support system [1], a guide rail system [2] and a hanging system [3]. The support system [1] comprises four upright frames and a horizontal frame. The guide rail system [2] comprises two longitudinal guide rails, multiple transverse guide rails and a guide rail hanger. The guide rail system [2] is mounted below the horizontal frame. The hanging system [3] comprises a rolling bearing frame, a tubular dynamometer and a connecting piece. Through the invention, the problems existing in simulation of the zero-gravity state of the environment orbit of the solar cell array and antenna of the satellite in the ground gravity environment and the like are solved, and beneficial effects of simple structure, convenience in use, strong adaptability and the like are obtained.
