Ground variable centroid zero-gravity simulation device and simulation method

Abstract

The invention discloses a ground variable centroid zero-gravity simulation device and a simulation method, solves the problem that an existing microgravity simulation device affects the performance of a space device, and belongs to the field of ground zero-gravity simulation of space. A spherical air bearing seat is placed on a base; 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 floats; the middle platform, a lower platform, a Z-direction movement module, a linear module fixing platform, a XY-direction movement module and a upper platform are sequentially connected from bottom to top; a mass center sensitive element and a mechanical arm connecting rod are arranged on the upper platform; a controller controls the XY-direction movement module, the Z-direction movement module and the spherical air bearing rotor to spray air according to the change of the mass center detected by the mass center sensitive element, so that the mass center of an integrated piece moves to the center of the spherical air bearing rotor, and mass center adjustment is achieved.

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...
