| 中文摘要 | 本文旨在探討高速陸地運輸系統的多電磁懸吊車輛與彈性導軌之間的相互動態響應問題。磁浮車輛被簡化成二維八自由度的系統,亦即包括視為剛性物體之車體部份和具有塊狀質量、線性彈簧和黏性阻尼的初級與二級懸吊系統。而導軌則假設是由一系列獨立的單跨距簡支梁所組成,文中以柏努利─尤拉梁的理論來模擬彈性導軌的特性,並利用模態分析法來求解彈性導軌之運動方程式。為了分析車輛電磁懸吊系統的數量,對車體垂直加速度比與俯仰方向角加速度比和導軌動態行為所造成的影響,因此根據運動方程式,以電腦來模擬車輛/導軌系統在各種不同電磁懸吊數量的情況下,對車輛和導軌穩定狀態之動態響應情形。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 | This study investigates the dynamic interactions between a vehicle and guideway of a high-speed ground transportation system based on magnetically levitated (maglev) vehicles. The guideway is assumed to be made up of identical simply supported beams with single spans and rigid supports. The vehicle is considered to be two-dimensional, with numerous degrees of freedom, representing the passenger cabin and primary and secondary suspensions of the vehicle with lumped masses, linear springs and dampings. The Bernoulli-Euler beam equation is utilized to model the characteristics of a flexible guideway. Guideway synthesis is based on a modal analysis method. Computer simulation is performed to investigate the number of vehicle suspension systems that affect the dynamic interactions between a vehicle and a discretely supported guideway. Finally, the various simulations are compared. |
