| Summary: | 碩士 === 大葉大學 === 自動化工程學系碩士班 === 92 === This study concentrates on using the technique of computer-aided engineering analysis in the design of bicycle structure of diamond shape. The von Mises stress distribution and fatigue life may be found, and a better structure can be obtained.
The solid model of such a structure is first established in PRO-E and then transfer to Workbench for finite element analysis. The model is composed of various parts which are circular tubes. The outer diameters are set as constant and the inner ones are defined as the parametric design variables. Selecting the minimal weight of the model as the objective function, and employing the algorithm provided in Workbench, the optimal set of these design variables are obtained.
