E-Bike馬達模態分析及最佳化
E-Bike motor modal analysis and optimization
摘要
近年來全球環境汙染問題日益嚴重，世界各國家均積極努力降低碳排放量。歐盟政府近年不但積極修改相關法規並且進行補貼措施，以鼓勵人們使用具有綠色環保概念的電動車輛。基於歐盟國民崇尚綠能對於短行駛距離之電動輔助腳踏車接受度也越來越高，也促使電動自行車產業發展迅速。隨著電動自行車產業迅速發展中在噪音、續航力、充電速度、使用者介面遇到發展瓶頸。本文將針對馬達共振噪音進行探討。首先以3D CAD軟體繪出整個馬達結構，使用有限元素分析軟體Ansys Workbench之模態分析模組找出馬達自然頻率，並與實驗數據進行比對，確認引發共振元件；再來針對共振元件使用實驗設計法進行最佳化設計；最後確認最佳化結果是否符合設計所需並再次檢視該設計參數是否會造成其它衍生性問題。

The pollution of the environment has become more serious in recent years. The countries of the world are trying to save energy and reduce carbon emission. The government in recent years not only actively to amend the relevant regulations and subsidies to encourage people to use electric vehicles(EVS). An increasingly high degree based on the EU advocate green travel for short distance power assisted bicycle, also contributed to the development of electric bicycle industry quickly. With the rapid development of electric bicycle industry in noise, endurance, charging speed, interface encountered development bottleneck. In this paper will discuss the motor noise. First to 3D CAD software to draw the whole motor structure, using finite element analysis software ANSYS Workbench modal analysis module to find the natural frequencies of the motor and with experimental data for comparison, confirm the cause resonance element; again for resonant element use experimental design method was the best design; finally confirm the optimal results are in line with design and re - examine the design parameters will cause other derivative problems.
