Abstract

The invention relates to and is applicable to the field of full ground physical simulation, in particular to a method for adjusting the mass center of a three-axis air bearing table based on a non-orthogonal structure. The method aims to solve the problems that in the prior art, adjustment of the mass center of the three-axis air bearing table requires manual leveling, time is wasted, and the adjustment accuracy of the mass center of the three-axis air bearing table is low. By means of the method, the mass center of the three-axis air bearing table can be adjusted to the position where the mass center of the three-axis air bearing table and the rotation center of the three-axis air bearing table coincide, so that the experiment table has high balance precision, the positioning accuracy of a three-dimensional mass center adjustment system of the experiment table is higher than 10 microns, and the using requirement existing when the experiment table conducts posture simulation on the ground is met; time for adjustment of the mass center is greatly shortened, manual operation is not needed, and adjustment time is shortened by over one time compared with the prior art.

Description

technical field [0001] The invention relates to the field of ground full physics simulation. Background technique [0002] With people's exploration of outer space, it has become a necessary step to develop and launch satellites by placing the developed satellites on the air flotation simulation platform for simulation tests, so as to reduce research costs and improve the success rate of satellite missions. The three-axis simulation platform is mainly used to simulate the attitude movement of aircraft and other equipment in a certain environment. The development of control technology and computer technology, as well as the development and application of new materials, make the simulation platform smaller in size, stronger in stiffness and higher in carrying capacity. In addition, the advancement of science and technology has greatly improved the control accuracy and position data accuracy of the simulation platform. Therefore, the three-axis air bearing table will no longe...
