論文摘要內容：
本論文主要是開發一無人化全地形車之車架結構，並完成整車系統整合設計與實作。無人化全地形車車架結構之輕量化分析，是結合拓撲最佳化分析及有限元素模型分析。本研究所開發之全地形車車架結構目標重量必須低於55 kg，而彎曲及扭轉剛性分別必須高於2000 N/mm與2000 N-m/deg。而車架結構之使用壽命，需可在農田路面下行駛超過5年。
本研究是採用Tosca拓撲最佳化分析軟體，來進行車架結構之輕量化分析。車架結構之剛性、強度及疲勞壽命分析，則是採用Abaqus之三維彈塑性有限元素模型。由分析結果得知，本研究所設計之車架結構重量為53 kg，彎曲剛性及扭轉剛性值分別為2421 N/mm與 2306 N-m/deg。疲勞壽命分析結果可得知，當本研究所開發之車架結構以時速3.6 km/hr 於農田中作業時，其疲勞壽命可達到5.42年。另外本研究也完成無人化全地形車整車系統之設計整合及實作。

The Contents of Abstract in this Thesis：
In this thesis, the vehicle system integration and the structure design for an unmanned all-terrain vehicle are developed and fabricated. The lightweight analysis process of the all-terrain vehicle structure combines topology optimization analysis and finite element model analysis. The design weight of the body structure is set to be less than 55 kg. The bending stiffness and the torsional stiffness of the body structure are design to be greater than 2000 N/mm and 2000 N-m/deg, respectively. The service life of the body structure should be able to drive on farmland roads for more than 5 years.
In this research, the Tosca topology optimization software is used for the lightweight analysis of the all-terrain body structure. The stiffness, strength, and fatigue life analysis of the body structure is based on the three-dimensional eleastic-plastic finite element model of Abaqus. The results indicate that the weight of the proposed body structure is 53 kg. The bending stiffness and the torsional stiffness of the body structure are 2421 N/mm and 2306 N-m/deg, respectively. The simulation results show that the fatigue life of the proposed body structure driving on the farmland roads at a speed of 3.6 km/hr can reach 5.42 years. In addition, this thesis also completed the integrated design of the vehicle system and fabrication of the unmanned all-terrain vehicle.
