中文摘要 | 本文旨在探討高速磁浮(Maglev)車輛與離散支承彈性導軌之間的相互動態響應 問題。磁浮車輛被簡化成包括視為剛性車體部份和具有線性彈簧、黏性阻尼的懸吊系統之二 維二自由度的半車(half-vehicle)模型;導軌則假設是由一序列獨立的單跨距簡支樑所建構 而成。文中依據車輛在導軌的運動特性,建立了三種導軌承載模式,並利用模態分析法求解 導軌之運動方程式組。 為了分析導軌跨距的長度和磁浮車輛的車體質量、懸吊系統的勁度及車輛的速度等參 數,對導軌及車輛藕合動態行為的影響,因此根據運動方程式組,以電腦來模擬車輛-導軌 系統在上面所提的各種不同系統參數的情況下,車輛和導軌穩定狀態之動態反應。並將電腦 模擬所得之結果作了比較分析。其結果應可提供車輛-導軌系統設計工作者在設計時之參 考。 |
英文摘要 | The purpose of this paper is directed towards an investigation of the dynamic interaction between a magnetically levitated (Maglev)vehicle and the guideway of a high speed ground transportation system. The vehicle is considered to be a two-dimensional system with two degrees of freedom featuring the rigid vehicle being suspended by linear springs and dampers. The guideway is assumed to be constructed by a sequence of simply supported beams with a single span and rigid supports. Three different modes corresponding to the loading conditions of the guideway are generated based on the motion characteristics of the Maglev vehicle. The equations of motion of the guideway system are derived and solved by the method of modal analysis. Computer simulation was also performed to investigate the parameters that may affect the behavior of dynamic interaction between the vehicles and the discretely supported guideway, such as the length of the span, mass of the vehicle, stiffness of the vehicle suspension, forward vehicle velocity, etc. Finally, comparisons among various simulation results were performed to provide basic design guidelines for Maglev vehicle-guideway systems. |
