Embodiment Construction

[0018] figure 1 It is a mechanical principle diagram for realizing the azimuth scanning self-balancing of the present invention; as figure 1 As shown in the embodiment, the centers of rotation of the load instrument m1 and the counterweight m2 are distributed on both sides, and rotate in opposite directions at the same time to cancel out the interference force. Among them, in order to eliminate the interference of torque disturbance, the product of the moment of inertia of m1 around the center of gyration and the product of gyration speed and the product of the moment of inertia of m2 around the center of gyration and the product of the angular velocity of gyration are equal in size and opposite in direction; The product of the angular acceleration is equal to the product of the moment of inertia of m2 around the center of rotation and the product of the rotation speed, but the direction is opposite.

[0019] Preferred embodiments of the present invention will be described be...

Abstract

The invention relates to a satellite scanning system and discloses a space scanning bracket with a self-balancing function. The space scanning bracket with the self-balancing function comprises an azimuth scanning bracket (5) which is arranged on an arc-shaped bracket (4), the azimuth scanning bracket is provided with two sliding rails and two sliding blocks, and the arc-shaped bracket (4) is provided with an internal arc and an arc-shaped sliding rail. A loading instrument (7) and a balance weight (1) are arranged on two sides of the azimuth scanning bracket (5) and do oscillatory scanning with speed in the opposite direction on the sliding rails of the azimuth scanning bracket (5) through rollers, the product of rotation inertia and rotation speed of the loading instrument encircling a rotation center and the product of rotation inertia and rotation speed of the balance weight encircling the rotation center are equal in number and opposite in direction. The space scanning bracket with the self-balancing function solves the problems of a complex control system, a high manufacturing cost and unreasonable structure design and the like existing in an existing scanning mechanism and achieves the beneficial effects of relieving the burden of the satellite attitude and the orbital control system, reducing the development cost, prolonging the satellite service life and the like.

Description

technical field [0001] The invention relates to a scanning system for satellite loads, in particular to a space scanning bracket with a self-balancing function. Background technique [0002] With the continuous development of modern science and technology, satellites have become an indispensable part of modern life. Among them, the main task of the space scanning system is to scan the observation area comprehensively and stably, and accurately telemeter data. Due to the high-speed operation of the satellite in outer space, according to the principle of conservation of momentum, the rotation of the scanning mechanism in all dimensions will definitely affect the operating attitude of the satellite body. According to the special needs of satellite work, the scanning mechanism has the following requirements: the mechanism can achieve a certain range of scanning, and the left and right swing and front and rear pitch must surround the same circle center; under the condition of ens...
