"本計畫針對燃料電池動力電動公車進行詳盡的結構動態分析，採用電腦輔助工程設計與分析(CAD/CAE)技術來建立電池動力電動公車底盤、車架、電池配重等結構，再以有限元素分析軟體LS-Dyna進行結構動態分析，以提供業界申請大客車結構認證之驗證作業。本計畫擬根據相關法規設計並建立燃料電池公車骨架結構之有限元素模型。由於燃料電池公車的整車結構佈置有其特殊性，且因為動力技術新穎，因此傳動系統與車架結構設計上與傳統公車有較大區別。本計畫將建立一計算平台模擬燃料電池公車靜動態強度及扭轉剛度之程序，進行整車骨架及載重狀態下根據法規規範設計其動態模式及結構強度。同時進一步在相同結構強度下，以期能使燃料電池公車之結構輕量化，可有效提高燃料電池使用的經濟性。"
This research investigates the dynamics characteristics of structural safe for a fuel cell passenger vehicle by using finite element analysis and numerical experimental modal analysis. Since the lack of original design data, all computer-aided design (CAD) data of the vehicle structure is established in this research by using the software. Computer-aided engineering (CAE) model is subsequently established by using software LS-DYNA. The CAD/CAE models include body and floor structures, chassis frame, axles, fuel tank, engine and transmission, etc. The mechanical properties of body structures are obtained from tensile tests. Normal mode analysis was performed to obtain the body rollover test and associated shapes deformation of the body structures, chassis frame, and full vehicle structures. More advanced, this project will improve the body structure of fuel cell passenger vehicle lighter in order to raise the economics of fuel cell life at same structure strength.
