    [[abstract]]目前全世界對於適路性車燈光形線上配光檢測技術,尚未有很嚴格的檢測,且國內對於前車燈光形檢測系統的機台,大多數都仰賴於國外,為了研發國內對於機台的製作能力。因此,本研究計畫將研發製作具備高速度、高精度快速定位的適路性車燈光形線上配光檢測機台,本計畫的主要工作分年敘述如下: 第一年的主要工作內容,首先,利用Optimus 找出適路性車燈光形線上配光檢測機台的最佳化設計,再以MSC 軟體分析為基礎,設計出快速高精度定位的適路性車燈光形線上配光檢測機台,並加工製作成實體。第二年的主要工作內容,是對適路性車燈光形線上配光檢測系統,進行軟體開發,將使用PC BASED 系統結合LabVIEW 和PLC,進行之控制。LabVIEW 主要是撰寫檢測光形部分、擷取照度值、RS-232 通訊協定、PLC 通訊協定…等等。PLC 主要是控制 X-Y 滑台動作、控制點光機、治具定位梢…等等。第三年的主要工作內容,是對適路性車燈光形線上配光檢測系統光學設計,利用光學原理,讓適路性前車燈光透過Fresnel Lens,顯現在測光板上,通過影像檢測區,使用CCD 做為影像擷取,在將擷取進來的影像分析,再與ASAP 光學模擬進行比較。本計畫將根據ECE 車輛法規,建立起光學檢測的參考模型,設計出一套可快速檢測適路性車燈光形的檢測系統開發。[[abstract]]Adaptive Front-Lighting System of headlamp isn’t has strict detection in the world. And so far, headlamps shape of detection machine almost from other countries. To develop the domestic capacity, that the production of machine. Therefore, the groundwork of this plan will research and development a high-speed and high- precision of detection machine. The groundwork of this plan will be narrated as follows: The first years: Using the Optimus to Optimal design and use MSC to proceed with the dynamic simulation and then manufacture.

    [[abstract]]導光柱(LGR)被用於車輛上已經越來越普遍,所以車燈燈具廠需要量產LGR以迎合這潮流。本計劃旨在建立一個系統性的方式,去找到LGR的最佳參數組合,且參數的水準種類為限制幾種規格及無設定量之隨機值。這些產品必須符合工業標準,並具有良好的性能。在這個多目標案例中,有兩個限制規格之水準因子,一個無設定量之隨機水準因子,和兩種光學性能表現,將採用實數型基因演算法(RGA)和簡化的灰關聯分析來進行最佳化。以RGA規劃、設計光學模擬實驗,並使用這些模擬中所收集到的數據,來處理和計算簡化的灰關聯分析。實驗結果中的光通量和平均差,可以被整理成一個單一的性能指標。因為有簡化,此計算過程速度比S/N-灰關聯分析還快。最後,將最佳參數組合與原始組進行光學模擬來相比其結果,我們可以得知光學性能的改善。本計畫之光學最佳化設計,具有以科學理論為基礎,並非只仰賴人員經驗判斷之優點,對於研究多目標最佳化之產學界有相當大之幫助及實用性,相關研究成果期轉移至國內產學界應用。[[abstract]]The light guide rod (LGR) has been used for the vehicles popularly so the automobile lamp industries need to have mass production on the LGR to match this trend. This plain aims to develop a systemic way to find the best parameter combination for LGRs, and the kinds of parameters are restricted levels and random levels. These products must meet industry standards and have good performances. There are two restricted levels factors, one random level factor, and two optical performances in this multi-objective case, which would be optimized by use of real-coded genetic algorithm (RGA) and simplified Grey relational analysis in this paper. The illuminance simulations for experiments are designed by RGA, and those collected data are used to process and estimate by simplified Grey relational analysis. The experimental results from illuminance flux and uniformity can be integrated into a single performance index. The evaluate flow is faster than S/N-Grey relational analysis. Finally, the best parameter combination of illuminance simulations are compared with the original set, we can know the optical effects are improved. The optical optimization design of this plain has advantage that is base on scientific theories, not just rely on the experience of personnel. For industry and academia, this multi-objective optimization is useful and practical. We look forward that this research will be applied in the domestic industrial and academic circles.[[note]]NSC101-2622-E327-016-CC

The novel actuator is applicable to the fields of manufacturing, assembling, examining, and aligning works for the miniaturized components of high-tech industry. The experimental works on the 1-DOF(Degree-Of-Freedom) setup have been carried out. It shows that the long-range positioning table could be actuated continuously by the electromagnetic force of the VCM and the impact force of the piezoelectric element, and hence it could behave as a long-range actuator with the long-range and nanometer positioning capability. According to the experimental results, the motion behaviors of the table were examined by changing several parameters, i.e., the waveform and the amplitude of the applied voltage, and the mass of the table. In addition, the proposed actuator will bring about a significant change in transferring the common and inexpensive pneumatic actuator into a high-tech and high added value product. According to the ultra-precision positioning ability, the proposed actuator is one of the fundamental tools for opening the era of nano-technology. It is expected that the developed technology in this project will make a great contribution to push forward with the development of our precision industry and increase the ability in global competitiveness
