現今電動自行車產業創新設計理念,跳脫一般刻板印象騎腳踏車是費力省時的概念,所以在自行車上增添助力馬達,到省力又省時的腳踏車,基於設計馬達需要降低成本、減少噪音、強度需符合規範,自行車廠商需要最佳化馬達設計,要將齒輪更改為複合材料的塑膠齒輪,由於要減少打樣的風險及成本,所以將使用有限元素分析,預先知道強度是否符合規範及產品使用壽命。 本研究先以3D CAD軟體繪出整個馬達結構,針對探討齒輪部份,使用有限元素軟體 Hypermesh 作柔性體的轉換,最後以ADAMS動態模擬軟體仿真行星齒輪組之運動過程,藉由ADAMS動態模擬軟體,計算出馬達運轉過程中齒輪的應力強度,之後由此模擬結果,可了解到由金屬更改為塑膠齒輪,強度是否依然能夠符合標準;也可以計算出產品使用的壽命。
Today the electric bicycle industry innovative design concept, the general stereotype cycling trip is laborious and time-saving concept, so adding booster motor on the bike, bike to the effort and time-saving design of the motor based on the need to reduce costs, reduce noise, intensity required compliant, bicycle manufacturers need to optimize the motor design, to change the gear composite plastic gears, due to the reduction of risks and costs proofing, so will the use of finite element analysis, to know in advance whether the intensity of compliance. In this study, the first 3D CAD software to draw the whole motor structure for Discussion gear part, using finite element software that converts Hypermesh flexible body, and finally to the motion dynamic simulation software ADAMS simulation of the planetary gear set of the process, with a dynamic simulation software ADAMS to simulate the stress intensity during motor operation of gears, with this analysis and simulation, you can learn to change from metal to plastic gears, strength is still able to meet the standards.
