摘要
本論文之目的為淑女車的結構分析，主要分為靜態分析、模態分析、動態分析三項，車架結構的設計對於其安全性與舒適性極其重要，本文利用Pro-ENGINEER繪圖軟體建構3-D實體模型，再匯入有限元素分析軟體ANSYS Workbench進行靜態、模態分析，之後再匯入MSC.Adams進行動態分析。 本文採用有限元素法ANSYS Workbench來探討車架本身之結構強度，其靜態分析之最大應力值應小於材料性質的降伏應力值，再將最大應力值集中點處做強度改良，使其最大應力值降低至符合安全值範圍。二為動態分析，使用MSC Adams分析軟體針對避震器彈簧係數做牛頓迭代法，再以振動國際標準法ISO 2631之準則對座椅Y方向加速度均方根值做牛頓迭代法以尋求最佳避震器彈簧彈性及阻尼係數，經多次迭代後求得最佳值。

The purpose of this paper is the analysis of the structure of Princess Bike. It is divided into static analysis, modal analysis and dynamic analysis. The design of frame structure is very important for its safety and comfort. In this paper, we use Pro-ENGINEER software to construct 3D Solid model, and then import the finite element analysis software ANSYS Workbench for static, modal analysis, and then import MSC.Adams for dynamic analysis. In this paper, the finite element method ANSYS Workbench is used to study the structural strength of the frame itself. The maximum stress value of the static analysis should be smaller than the stress value of the material. Then, the maximum stress value is improved and the maximum stress value is reduced To a safe value range. For the dynamic analysis, the MSC Adams analysis software was used to do the Newton iteration method for the spring coefficient of the shock absorber, and then the vibration of the international standard method ISO 2631 was used to adjust the Y-direction acceleration of the seat to the Newton iteration method to find the best shock. The results show that the best spring constant and damping coefficient.
