Ground variable center of mass zero gravity simulation device and simulation method

Abstract

The ground variable center of mass zero-gravity simulation device and simulation method solve the problem that the existing micro-gravity simulation device affects the performance of space devices, and belong to the field of ground zero-gravity simulation in space. The spherical air bearing seat is placed on the base of the present invention; the spherical air bearing seat supports the spherical air bearing rotor, and a layer of air film is formed between the middle platform and the spherical air bearing rotor, so that the middle platform is air-floated; the middle platform , the lower platform, the Z-direction movement module, the linear module fixed platform, the XY-direction movement module, and the upper platform are connected from bottom to top in sequence; The detected change of the center of mass controls the XY direction movement module, the Z direction movement module and the air injection of the spherical air bearing rotor, so that the center of mass of the integrated part moves to the center of the spherical air bearing rotor to realize the adjustment of the center of mass.

Description

technical field [0001] The invention relates to the field of ground zero-gravity simulation in space, in particular to a ground-variable center-of-mass zero-gravity simulation device and a simulation method applied to a space-variable center-of-mass device. Background technique [0002] With the continuous development of aerospace technology, the tasks that humans can achieve in space are more diverse, and the operating equipment is also becoming larger, more complex, and more scalable. When controlling a large and variable space device such as a space station connected to a space manipulator, it is necessary to consider that when the manipulator moves, the center of mass of the entire space device will change, and the change of the center of mass means the coordinate transformation between each sub-body The relationship has changed. At this time, if the previous coordinate transformation relationship is used, the control will deviate, which may lead to the failure of the sp...
