Vibration detection device and method for multi-rotary-joint space solar power station

Abstract

The invention discloses a vibration detection device and method for a multi-rotary-joint space solar power station. The vibration detection device comprises a multi-rotary-joint space solar power station structure, a posture fixing suspension structure, a vibration excitation structure and a vibration detection structure. The multi-rotary-joint space solar power station is fixed to the posture fixing suspension structure to keep a space form, the vibration excitation structure comprises two vibration exciters, the two vibration exciters are connected with the multi-rotary-joint space solar power station and are used for exciting the multi-rotary-joint space solar power station to generate vibration, and the vibration detection structure comprises three groups of binocular vision units andis used for detecting mark points on a solar panel array and an antenna of the multi-rotary-joint space solar power station so as to obtain vibration information of the structure.

Description

technical field [0001] The invention relates to the field of vibration detection and analysis of space expandable structures, in particular to a vibration detection device and method for a multi-rotation joint space solar power station. Background technique [0002] With the continuous increase of human demand for energy and the continuous reduction of fossil energy that can be developed and utilized on the earth, people are actively seeking for sustainable development and utilization of clean energy. Solar energy is the main source of energy for the earth, how to develop and utilize solar energy has always been one of the hot topics in the development and research of clean energy all over the world, and building solar power plants is an ideal and easy-to-achieve solar energy utilization method. However, due to the large energy attenuation of the sun's rays when they pass through the earth's atmosphere, plus the earth's rotation will cause the earth to appear day and night a...
