Description

technical field [0001] The invention relates to ground support equipment for spacecraft such as satellites, in particular to a zero-gravity suspension type deployment test device for solar cell arrays and antenna deployment tests of spacecraft such as satellites. Background technique [0002] In the development process of spacecraft such as satellites, the test of solar cell array and antenna is a basic and indispensable test content. Since the spacecraft is in a state of weightlessness when orbiting, the zero-gravity state that simulates the orbital environment when the solar array and antenna are deployed on the ground is called a key factor for the success of the experiment. At the same time, the deployment trajectory of the solar cell array and antenna is also an important factor to be considered for the test ground support equipment. [0003] At present, most of the deployment tests of solar cell arrays and antennas use air-floating deployment test devices. The overal...
