Description

technical field [0001] The invention relates to a small satellite installed with a flexible solar wing to perform overall dynamic simulation on the ground, in particular to a microgravity dynamic loading simulation mechanism on the ground of a satellite. Background technique [0002] At present, the ground simulation of small satellites at home and abroad mainly adopts the semi-physical simulation method of the air bearing platform, and there is no overall simulation of the satellite with flexible accessories. Most of these simulation systems use the momentum wheels or nozzles installed on the air bearing platform to simulate the disturbance of the space, without realizing the separation of the disturbance loading device and the air bearing platform, and introducing the micro-vibration of the loading device, which is harmful to satellites with large flexible accessories. The study of the state of motion under disturbance and the verification of the control algorithm bring er...
