Static balance testing device and method of high-precision gyroscope suspension system

Abstract

The invention discloses a static balance testing device and method of a high-precision gyroscope suspension system. The device comprises a controllable lifting gyroscope suspension system support, a laser emitter, a receiving plate, a high-resolution programmable industrial camera, a positioning support of the high-resolution programmable industrial camera, a high-precision level meter, a transparent glass cover for protecting the suspension system, and a computer. Method comprises the following steps of accurately capturing the motion track of a feature point; calculating the static balance residual amount of a gyroscope suspending system by determining the motion track of the feature point, namely the gravity center deviation; and converting parameters which cannot be observed directly into observable parameters so as to provide a scientific basis for the determination of the static balance residual amount of the gyroscope suspending system. The determination of the static balance residual amount of the gyroscope suspending system can be used for providing the scientific basis for the research and production debugging of a high-precision gyroscope with the precision superior to + / -5s; the installation and debugging efficiency are improved; the requirement of the high-precision gyroscope on operation experience of installation and debugging personnel is lowered.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping instruments, and relates to a high-precision gyroscope suspension system static balance testing device and method. Background technique [0002] High-precision (orientation accuracy is better than ±5″) gyroscope is the necessary equipment for the construction of long tunnels (such as subsea tunnels, subways, etc.) and the initial orientation of long-range missile carriers. In the "New York to Beijing" long tunnel construction and intercontinental missile Initial orientation errors of ±1" in launch often result in unacceptable in-plane position deviations. Therefore, the high-precision gyroscope is an essential device for my country's national economic construction and national defense and military applications. Although there are many types of gyroscopes, including magnetic levitation gyroscopes, fiber optic gyroscopes, laser gyroscopes, micromechanical gyroscopes, flexible gyroscop...
