Analysis Of Parabolid Antenna Sunshine Temperature Effects And Layout Optimal Of Temperature Sensor

This paper based on a large-diameter parabolic antenna for the study and carriedout research in two areas: temperature effects upon Large-Diameter Parabolic Antennain sunshine environment and the layout optimal of a fixed number of temperaturesensor based on genetic algorithm.In the area of analysis of sunshine’s temperature effects of Large-diameterparabolic antenna:studied a Large-diameter parabolic antenna’s temeprature anddeformation variation law using the finite element method.considered one of the mostadverse weather,that is, the In the area of analysis of sunshine’s temperature effects ofLarge-diameter parabolic antenna whole point of the summer solstice day time’s solarradiation, air convection, longwave radiation and ambient occlusion shadow of avariety of boundary conditions,carried out the transient analysis of the reflector paneland the frame structureand got the sunshine temperature field of a specific day.，finallydetermined the temperature field and deformation field variation law with timeaccording to the result.The layout optimal of a fixed number of temperature sensor sonsists of twoparts:one is Interpolation theory of space-based reconstruction of temperature field.According to the theory of spatial interpolation, using inverse distance weightedinterpolation,made use of a finite number of nodes at a time interpolation to restore thetemperature to the temperature the rest of the temperature of the unknown node andmeasured the merits of the interpolation results Comparing to root mean squareerror.The second one is the layout optimal temperature sensor based on geneticalgorithm. For a moment the results of temperature field, to the theoretical basis of thegenetic algorithm and fixed the number of the reflector panel’s temperature sensors, tooptimize the temperature sensor arranged point through genetic algorithm selection,crossover and mutation operators.The study has shown that the results of temperaturefield interpolation to restore the root mean square error decreasing, as the geneticalgorithm genetic algebra increases, That means optimize the layout of the results pointclose to the optimal solution constantly.At present, the research on the above is just beginning, for this situation, thepaper conducted a preliminary attempt to explain relevant theory and research methods. The paper provides valuable guidance to improve the thermal-structural design forLarge-Diameter Parabolic Antenna.
