Embodiment Construction

[0044]The basic idea of ​​the present invention is: according to the deviation between the center of mass and the elastic center of the actual product of the strapdown inertial measurement combination, which affects the use accuracy of the product, a device for adjusting the position of the center of mass of the strapdown inertial measurement combination is proposed. The symmetrical design and the matching method of some parts can ensure that the center of mass of the rotating part of the device is on the axis of rotation, ensuring that it can truly reflect the deviation of the center of mass of the product to be tested. The product will rotate under the action of gravity and finally stop at the vertical position of the center of mass. After the first installation, adjust the deviation of the product with the center of mass on the vertical axis of rotation in the direction of its X and Z axes, and adjust the center of mass to the axis of rotation of the device. The standard for...

Abstract

The invention provides a device, adjustment method and application for adjusting the position of the center of mass of a product. The device includes a bottom plate, a base, a rotating system, and a connecting weight system; It is installed between two bases and has only one degree of freedom of rotation. The transfer weight system is installed on the rotation system, so that when the product is not clamped, the center of mass of the rotation system and the transfer weight system is on the rotation axis of the rotation system. Above; the product to be adjusted is clamped by the transfer counterweight system and fixedly connected with the transfer system. By adjusting the product, the elastic center of the product is guaranteed to be on the rotation axis of the rotation system. The standard of leveling is that the product can be stationary at any position around the rotation axis. , will not rotate due to center-of-mass deviation.

Description

technical field [0001] The invention relates to a device for adjusting the position of the center of mass of a product, especially a device for adjusting the position of the center of mass of a strapdown inertial measurement combination, more particularly, a structural device for adjusting and eliminating the deviation between the center of mass and elastic center of a strapdown inertial measurement combination . Background technique [0002] The inertial measurement device is mainly used in the navigation, guidance and control system to measure the motion parameters of the aircraft (vehicle) in real time, and the guidance and control system calculates the relevant control commands based on these real-time measured motion parameters (such as three-dimensional position, speed, attitude) , to control the attitude change of the aircraft and guide the aircraft to fly along the predetermined trajectory. [0003] The working environment of the strapdown inertial group (hereinafte...
