Numerical Analysis On Distributions Of Temperature Field In Single Wing Of Flexible Solar Array

This thesis focuses on the structure and symmetry of the single flexible wingpanel composed of solar cells and establish a finite element model of the singlewing panel whose size is one-fourth of the practical single wing panel. Based onthe thermal characteristics of the environment of the low Earth orbit, then, thisthesis give full consideration to the factors of the solar radiation, infrared radiation,the Earth reflection intensity of sunlight and other sources of heat, the fact that theenvironment of outer space is cold and dark, as well as four different states ofphotoelectric conversion efficiency of solar cells. With using the simulationsoftware Marc2003, under different conditions, we acquire the temperaturedistribution of the substrate and the solar cells of the multilayer flexible solar arraywing panel within the specified operating cycle. In addition, under the differentconditions of conversion efficiency, we get the temperature curve over time ofevery typical plot in the panel and analyze the distribution of temperature field ofthe single flexible wing panel. When the temperature of single flexible wing panelreach the upper limit, the upper limit temperature will decline as the efficiency ofthe panel increases. And on the other hand, when the temperature of single flexiblewing panel reach the lower limit, solar cells of the panel won’t work at all, so thetemperature will keep steady. Above all, this thesis provide the useful referencedata which could be used to calculate and analyze the thermo-mechanical stressand strain of the single flexible wing panel.
