中文摘要 | 本文在前半部對內變速器的傳動系統,亦即行星齒輪系進行設計考量分析。後半 部則把這些考量作為限制函數,以速比範圍最大化為目標函數為範例,在不改變行星齒輪的 安排下,利用最佳化的軟體,以求得行星齒輪系最佳參數值。 |
英文摘要 | This paper describes a formulated process for transmission system optimization in the multi-speed hub for the bicycle, i.e. optimization on the specified arrangement of the planetary gear train. The maximization of the speed-ratio range is selected as the objective funciton for demonstration. The geometric conditions and the performance requirements of the planetary gear train are defined as constraints. A sequential quadratic programming scheme (SQP) using modified branch-and-bound method (BBM) for discrete optimization is applied. The addendum modification coefficients are applied for each gear and pinion to decrease the structure size and enhance gear tooth strength. Results are shown that the transmission capacity, defined as the ratio of the maximum speed-ratio to the minimum speed-ratio, can be enhanced by 30changing the arrangement of the planetary gear train. |
