碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 102 === Nowadays, the solar energy has become an important and clean alternative energy in depletion of gas. The development and application of photovoltaic system that can transfer and absorb efficiently the solar power energy have become a popular research issue. The solar tracker can track the azimuths of the sun in order to maximize the absorbing of the solar energy in photovoltaic panel. The solar tracker is better than fixed solar tracker. In order to improve the efficiency of the absorbing of the solar tracking system, the design of the solar tracking system play a significant role. In this article, the sun's azimuth with respect to time is considered as the ideal function of the solar tacking four bar linkages which have output and input angles corresponding to the relationship between the sun's azimuth and time. The planar four bar linkage and RSSR spatial four bar linkage are designed for the solar tracking linkages in this thesis. The dimensions of solar tracking planar four bar linkages are synthesized by three, four and five precision-point synthesis method and differential evolution (DE) algorithm, respectively. In addition, the structural errors and tracking efficiency of the synthesized linkages are investigated and compared among the precision-point synthesis methods and DE. The dimensional synthesis of solar tracking RSSR spatial four bar linkage only use DE and the structural error and the tracking efficiency are investigated. Furthermore, compared with the optimimum design of planar four bar linkage, the synthesized results of solar tracking RSSR spatial four bar linkage is more high accuracy and high tracking efficiency.
