Abstract

The invention discloses a measurement and monitoring method for centroid skewing permitted interference of a multi-axis support air floating platform and belongs to the technical field of an ultra-precise apparatus platform. The invention solves the problem that an existing support platform is limited in leveling state and is narrow in the range of application. The measurement and monitoring method comprises the steps that a centroid offset threshold is firstly set, a centroid offset G (x0, y0) is compared with the centroid offset threshold, and when the centroid offset G (x0, y0) is less than the centroid offset threshold, the telescopic length of each support leg is compensated; when the centroid offset G (x0, y0) is greater than the centroid offset threshold, nozzles of air feet are controlled to spray air, so as to enable a chassis platform to carry out translational motion in a horizontal concrete foundation and move along with the load on the chassis platform, so that the relative offset (x2, y2) is adjusted until the centroid offset G (x0, y0) is adjusted to be in the range of the centroid offset threshold. The measurement and monitoring method for centroid skewing permitted interference of the multi-axis support air floating platform is applicable to the measurement and monitoring of centroid skewing permitted interference of air floating platforms.

Description

technical field [0001] The invention relates to a measurement and monitoring method for the allowable interference of the center of mass offset of a multi-axis supported air-floating platform, and belongs to the technical field of ultra-precision instrument and equipment platforms. Background technique [0002] In modern society, a platform with high flatness is often required. For example, in full-physics simulation experiments such as space rendezvous and docking, ground measurement, navigation, network communication, and formation control, it is necessary to support the entire ground simulator and provide a basic platform for ground simulation experiments. ; Provide platform support for physical simulation tests such as formation satellite ground test verification and control algorithm verification analysis. Since the platform may be in a tilted state due to the unevenness of the large-area horizontal base when it is moving or stationary, it is not conducive to providing ...
