由於自行車現已蔚為風潮,進而使單車的配備不斷推陳出新,而自行車的核心則是在於傳動系統這部份,因此研究自行車傳動系統在具有負載的作動下,了解各不同狀況對於運動員的腿部,運動特性曲線與分析其應力的變化是一非常重要的課題。 本研究是利用有限元素分析軟體Simulation來分析人體腿部在不同參數下之運動研究,其中改變的參數為:(1)座椅高度、(2)路況、(3)運轉狀況等參數來進行運動分析,先使用SolidWorks來建構人體與自行車之模型,再以有限元素分析軟體Simulation分析取得角加速度、角速度及應力分析後的結果,最後根據分析的結果統計各參數對於腿部之影響。
Since the bike has become a trend, and thus make a bicycle equipped with continuous innovation, while the core of the bicycle is that this part of the transmission system, so the research that has bicycle transmission actuation under load, to understand the different conditions for the athletes legs movement characteristic curve analysis of changes in their stress is a very important topic. This study is the use of finite element analysis software to analyze motion Simulation study of human legs under different parameters, which change the parameters as follows: (1) seat height, (2) road conditions, (3) operating conditions and other parameters for motion analysis , first use SolidWorks to build the body and the bike model, then the finite element analysis software Simulation analysis results obtained angular acceleration, angular velocity and stress analysis, and statistics for the leg of the parameters affecting the results of the analysis.
