摘要


本研究目的主要設計出一種機構模擬真人騎自行車,可用於長時間且連續的動態疲勞測試。目前市面上有相當多制式的自行車檢測設備,用以檢驗自行車各部位的強度與可靠度,以達到法規的基本要求。為不同的需求,部分業者更會進一步引進客制化動力測試設備。但不論是制式或客制化的設備,大部分設備的動力輸入皆不是模擬真人騎自行車的狀態,以導致測試上盲點。因此,本研究的目的主要共軛原理設計一特定的凸輪,再搭配四連桿機構,建構出一套模擬真人騎自行車的測試機構,可長時間且連續的進行疲勞測試。 本研究機構設計,有將機構分別以模擬部分與實體部分進行運轉,初步取得結果,無論是運動可行性,運動方式,主動件與從動件的轉速是否相同等與機構設計之初希望達到的目的皆有符合。

In order to test the performance and reliabilities of a bicycle, it is necessary to perform a test equipment, in such a way that the loadings, fracture, fatigue, et al. can be tested out. The research proposed a test mechanism to simulate a real human riding by using a 4-bar linkage and a cam. The output pedaling speed keeps constant speed base on a given constant input speed of the cam. Consequently, if a test equipment consisting the proposed mechanism, the test condition will be as similar as a human riding, and additionally a continue test, which can check the reliability and fatigue, can be easily applied. The design of research institutions respectively for analog portion and entity portion operated test preliminary results obtained whether it is institutional feasibility of operation or the overall movement mechanism and Cam and crank speed is equal to or not…both reached.
