摘要


本論文主要研究太陽能車用鋁合金輪圈之強度,依照日本自動車標準組織對於機車輪圈的規範要求,以有限元素分析模擬規範內垂直落下撞擊測試及彎矩疲勞耐久測試,瞭解其在測試過程中的應力應變分佈情形,並以應變破壞理論及疲勞壽命理論,作為判斷輪圈是否發生衝擊破壞及疲勞破壞的依據。而分析結果顯示落下撞擊模擬對輪圈只造成撞擊處胎環凸緣塑性變形、彎矩疲勞耐久模擬對輪圈造成最大von Mises等效應力低於材料的疲勞限,都顯示輪圈之設計為安全的且符合規範要求。

This research is studied in the strength and fatigue property for the solar vehicle aluminum wheels. According to the light alloy motorcycle wheel standard of Japan Automotive Standard Operation (JASO), finite element analysis method is applied to simulate the impact test and the bending fatigue test of the standard. During the process, the stress and the strain distribution were observed, and then the strain fracture theory and the fatigue life theory are used for the criterions to guide if the wheel occurs fracture and fatigue. Due to the analysis results, the impact test simulation only causes plastic deformation in the rim near the impact point, and the Maximum von Mises stress is below the endurance limit stress of the material in fatigue test simulation. Both of the results show the design were safe and satisfy the requirements of the standard.
