本研究計畫為反射式太陽能集光模組最佳化設計與製作分析，基本架構是由兩圓錐面鏡組成，主要反射面為拋物面，分別搭配的兩種次要反射面：雙曲面、橢圓面去作設計。一開始我們預計先自建模組光線追跡與分析程式，簡單且迅速的求出各種規格並做初步分析，接著找出系統的最佳參數。而當入射光角度與集光模組有偏差，將導致光斑位置偏移、產生誤差，故設計出不同規格的模組之後，再對追蹤角度的容忍做分析與改善。且為了使集光模組容易製造組裝，我們將會設計雙反射多環型集光模組，將原先設計的曲面做分段線性化，再用自建程式分析與設計。最後再配合設計結果，對製作組裝作初步公差分析。第一年我們利用自建程式來設計集光模組參數，針對不同f-number做NA與集光比、NA與光斑大小、NA與曲面二孔徑、NA與兩曲面距離等做快速分析與參數最佳化，並用光學軟體去模擬理想與實際太陽光源模組的集光結果。接著根據實際光源之角度偏差對集光比與均勻性的影響，加入非球面高階項係數以減低因偏差角度而造成的光斑誤差。第二年則是延續第一年對追蹤角度的公差分析設計一個補償透鏡，目的在於降低因偏差角度造成的光斑位置誤差，以減少接受器之收光面積。接著針對雙反射多環型集光模組自建一些光線追跡與分析程式，簡單、迅速的初步分析；再使用光學模擬軟體，進一步確認數據，以達到最佳的結果。並對製程的公差、環境對系統造成的擾動等因素，做初步的分析探討。 ; This project is “The optimal Design and manufacturing analysis of solar concentrator module for double reflective mirrors”. The basic structure consists of paraboloidal primary mirror and hyperboloidal/ellipsoidal secondary mirror are used to design the axial symmetry solar concentrator. First, we expect to establish ray-tracing and analysis in our own program to efficiently and quickly solve any specifications and initial analysis, then find out the system optimal parameters. However, when the incident angle has deviation with concentrator module, it makes spot position shift and produces error. So after solving any specifications of concentrator module, we will make analysis and modification of track angle tolerance. And for the purpose of the concentrator module to be fabricated easily, the curves or curved surfaces being designed are composed of many straight lines or planes that called “double reflective many rings type concentrator module”. Then using self-developed program to analyze and design. Finally, we operate in coordination with the result of design to make initial analysis for manufacture and fabrication. In the first-year project, we will use the self-developed program to design parameters of concentrator module. In accordance with different f-number to quickly analyze and optimize concentrator ratio with NA, spot size with NA, the surface size with NA and distance of the two surfaces with NA. We also use optical software to simulate the concentration of the module in the ideal and real solar source. Then according to the incident angle deviation of real solar source concerning with concentrator ratio and uniformity, we design the high-level terms coefficient of the aspheric surface to reduce spot position error caused by the incident angle deviation. In the second-year project, we design a compensative lens to continue first-year project of track angle tolerance analysis in order to reduce spot position error caused by the incident angle deviation to lead to decrease received area of the detector. Then we will use our programs to make ray-tracing and analyze the parameters simply and fast of the double reflective many rings type concentrator module, and use optical software to verify and optimize. We finally make initial analysis of the manufacturing tolerance and environmental perturbation. ; 研究期間 9808 ~ 9907
