    摘要註: 本文目的為建立車輛-橋梁-風耦合系統分析程序與模型並進行動力分析。車輛-橋梁-風耦合系統振動行為為時變問題,本文將車輛視為序列式懸吊質量系統,並使用有限元素法為基礎理論的分析軟體進行模型建置與分析,本文首先說明有限元素法梁元素理論與應用,並將車輛模型簡化為懸吊質量系統,再對輪軌接觸行為模擬與建置,建立車輛-橋梁耦合系統並以VBI元素作為比較。在耦合系統的建立後對(1) 橋梁跨距與(2) 車輛速度;以及(3) 車輛形式三部分進行動力分析求得橋梁與車輛反應,其中車輛形式分為單一車輛、序列式車輛以及連續序列式車輛三種形式。在固定橋梁跨距分析中獲得橋梁反應與車輛速度呈正相關結果;在單一車輛與序列式車輛兩種車輛形式中進行車速與車輛反應比較,結果顯示車速與車輪反應呈負相關而車速與車輪加速度成正相關;另外也獲得橋梁反應與跨距呈正相關之結果,與材料力學基本理論相符合。而序列式車輛以不同車速進行分析,從橋梁反應發現相消現象,而在車輪加速度反應上發現放大效應。由以上結果得知本文所提出的車輛-橋梁耦合系統能成功分析橋梁與車輛動力反應,完成車輛-橋梁-風力耦合系統建制。 The purpose of this article is to establish an analysis producer of vehicle-bridge-wind coupled system, and modeling. After finish the model establishing, dynamic analysis is accomplished. The vehicle system is considered to sprung mass system in this article. The finite element method analysis software is used to establish the model and analyzed it. Beam element theorem and application in finite element method is described first in article. The method of simplifying the vehicle to sprung mass system is talked about second. The third part is to establish and model the behavior of contact between track and wheel. Finally the vehicle and bridge coupled system is established to compare to the results used by vehicle-bridge interaction(VBI) element method at past paper. After the coupled system is accomplished , (1)the bridge span length, (2)vehicle speed, and (3)the modes of vehicle are focus to make dynamic analysis and calculate the responses of bridge and vehicle. The modes of vehicle are included to single vehicle, serial vehicle, and continuous serial vehicle. The bridge response and vehicle speed are positive relationship under constant bridge span length. Within single and serial vehicle analysis compared, the vehicle speed and the response of wheels are negative relationship but vehicle speed and the acceleration of wheels are positive relationship. The response and span of a bridge are positive relationship to match the basic sense of material force theorem. Using different speeds in serial vehicle analysis, the cancellation phenomenon is happened in the response of bridge, and the amplification phenomenon happened according to observing the acceleration of wheel. Among these results, vehicle and bridge coupled system is accomplished successfully and analyze the dynamic responses of vehicle and bridge.
