Application of LDV in vibration analysis of satellite solar panel
Satellite solar panel bears with crucial responsibility in supplying energy while satellite orbits the moon. Through analyzing the vibration mode of solar panel, the structures natural frequency and inherent vibration vector can be obtained, which is of vital importance to structure dynamic modification, structure optimization design and fault diagnosis.This article summarizes the experimental results and analysis of solar panel under vibration with the aid of LDV. Through binary channel fast Fourier Transform (FFT), combined with modal analysis theories and software analysis system, a modal model of solar panel is built. Such an modal model provides a basis for the determination of the physical and structural parameters in the solar panel design of a satellite and provides an analysis method for the reliability validation of the design and the operating reliability of the satellite.
