The invention discloses a multi-target six-degree-of-freedom microgravity ground simulation system and a using method, which belong to the technical field of ground microgravity simulation test. Including high-rigidity gantry, discrete guiding system, 6-DOF simulation platform, motion measurement system, high-rigidity gantry is fixed on the ground, discrete guiding system is installed on the lower surface of high-rigidity gantry, 6-DOF simulation platform It is slidably connected with the discrete guide system and suspended below the discrete guide system, and the motion measurement system is installed around the high-rigidity gantry. The present invention allows no less than five six-degree-of-freedom simulation platforms to perform ground simulation motion at the same time, adopts a combined two-dimensional motion system and a vertical lifting system to track the spatial position, the three-degree-of-freedom rotation system adapts to the spatial attitude, and the constant force maintaining system provides micro The gravity environment enables the whole system to adapt to the six-degree-of-freedom load and the large-scale maneuvering and multi-load staggered motion simulation.
Description
technical field [0001] The invention relates to a multi-target six-degree-of-freedom microgravity ground simulation system and a using method, and belongs to the technical field of ground microgravity simulation test. Background technique [0002] With the continuous development of space science and technology, whether it is near-Earth navigation or deep space exploration, the frequency of spacecraft research and development is getting higher and higher, the system functions are becoming more and more complex, and the frequency of verifying new technologies and solutions is increasing. However, spacecraft have high technical risks, complex system functions, high launch costs, and large losses due to test failures. In order to minimize the losses caused by spacecraft failures or failures, it is particularly important to ensure high spacecraft reliability. Therefore, it is the basic guarantee for the success of the launch mission to conduct as many test simulations based on th...
