隨著節能減碳的政策議題漸漸被重視，越來越多民眾購買自行車的意願逐漸提升，自行車主要結構為骨架、把手、腳踏板、煞車系統、傳動系統、車輪及其他裝置等，其中以骨架的設計為影響整體結構安全最重要的因素。本文將應用田口方法來探討自行車結構的安全設計，在滿足限定條件與目標函數之最佳化設計問題。其設計目的在於求得的最大應力值不得高於材料的降伏應力值之限制條件。實施方法，首先選擇適當直交表來規劃設計參數之值，結合有限元素套裝軟體ANSYS workbench，分析自行車骨架各部份所受的應力值，並且應用信號/雜音(S/N；Signal to Noise Ratio)來評估目標函數的設計性能是否符合限制條件，再由控制因子效果分析及變異數分析，來確認設計參數對目標函數影響程度。最後有效處裡設計因子對多目標互相牴觸的最佳化問題，且有效的降低結構的應力值，並節省製造成本。
With the Energy Saving and Carbon Reduction, more and more people will gradually raise to buy a bike. Main of bike structure to the skeleton, hand, foot pedal, brake systems, transmission, wheels and other institutions, of which the skeleton designed to affect the overall structural safety of the most important factor. This article will explore the application of Taguchi Method to the structural safety of bicycle design, to meet the qualification and the objective function of the design problem. It is designed to obtain the maximum stress shall not exceed the Yield stress of materials limitations. Method of execution of this thesis select the appropriate orthogonal arrays to plan the design parameters of the value of finite element software package ANSYS workbench to analyze the various parts of a bike framework synthesis suffered stress and using the signal / noise (S / N：Signal to Noise Ratio) to assess whether the performance of the objective function of the design constraints limit line and then by the controllable factors effect analysis of variance analysis to confirm design parameters influence on the objective function. In the final of designed of effective factors on the multi-objective optimization of awkward questions and effectively reduced the structural equivalent stress and save manufacturing costs.

With the energy and carbon reduction policy issues has been emphasized, more and more people will gradually raise to buy a bike, bike main structure of the skeleton, hand, foot pedal, brake systems, transmission, wheels and other devices, of which the skeleton designed to affect the overall structural safety of the most important factor. This article will explore the application of Taguchi method to the structural safety of bicycle design, to meet the qualification and the objective function of optimal design problems. It is designed to obtain the maximum stress shall not exceed the material yield stress value constraints. Implementation of the method, first select the appropriate orthogonal table to plan the design parameters of the value of finite element software package ANSYS workbench, all part of the skeleton of a bike suffered stress, and using the signal / noise (S / N; Signal to Noise Ratio) to assessment of the objective function meets design performance constraints, and then by the control factor effect analysis, and variance analysis to confirm design parameters influence on the objective function. Department in the final design of effective factors on the multi-objective optimization of awkward questions, and effectively reduce the structural stress, and save manufacturing costs.參考資料： 我是英文老師

Reduces the carbon along with the energy conservation the policy subject to take seriously gradually, more and more populace purchase bicycle's wish to promote gradually, the bicycle primary structure for the skeleton, the hand, the foot board, brakes the system, the transmission system, the wheel and other installments and so on, take skeleton's design as the influence overall construction security most important factor. This article will discuss the bicycle structure using the field mouth method the safe design, is satisfying of optimization of design question the definition condition and the objective function. Its design goal lies in the biggest stress which obtains not to be worth being higher than the material to fall bends down of limiting condition the stress value. The implementation method, first chooses is perpendicular to the table to plan value of suitably the design variable, union limited element coverall software ANSYS workbench, analyzes stress value which bicycle skeleton various parts receive, and using signal/static (S/N; Signal to Noise Ratio) appraises the objective function the design performance whether to meet the limiting condition, again by the controlling element effect analysis and the variance analysis, confirms the design variable to the objective function influence. Finally effective place in designs the factor the optimization question which 牴 touches mutually to the multi-objectives, and effective reduces the structure the stress value, and saves the production參考資料： YAHOO奇摩 翻譯
