Abstract:	近年全球暖化現象造成地球氣候變遷反常，也嚴重危害到地球上生物存活環境，「節能減碳」不再是口號，也成為各已開發國家積極努力的目標。磁浮運輸因具有「低耗能、低噪音、低環境衝擊」的環保特性，不少國家均將磁浮運輸視為未來下一代導軌型運輸的重要交通設施。目前，世界上對磁浮運輸的研究，雖以德、日為首，中國與韓國近年也投入大量人力與物力，進行磁浮運輸相關課題的研究。例如，2002 年，上海市－浦東機場之間的高速磁浮線營運，標示著磁浮運輸紀元的到來；2005 年，日本愛知世博會的低速區域磁浮運輸(Tubo Kyuryo Line)，則代表著具有高科技象徵的磁浮運輸科技，已進入我們生活的實用階段；2008 年，韓國也開始積極地投入磁浮運輸的研究，目前已在大田(Daejeon)完成首條磁浮運輸 (UTM-02)的示範線。目前有關磁浮車之營運系統，主要有兩大系統：(1)德國Transrapid 磁浮列車系統，主要是以電磁懸浮式(electro-magnetic suspension system，簡稱EMS) 互吸型的磁浮機制為主，其磁浮間距(levitation gap)為0.5~2 公分之間，車體由分佈型的磁浮力所支撐； (2)日本的高速磁浮列車MLX 系統，主要是以電動懸浮式(electro-dynamic suspension system，簡稱EDS)互斥型的磁浮機制為主，其磁浮間距為10~15 公分，車體由集中型的磁浮力所支撐。針對上述之磁浮運輸的研究，計畫申請人，過去數年間雖一直專研輪軌式的高速鐵路車/ 橋互制振動(vehicle/bridge interaction dynamics)的研究。惟面對此一未來運輸趨勢，擬就磁浮運輸中的車/導軌振動與控制主題，提出三年的先導性研究計劃。整個計劃研究主題歸納如下： 1. 磁浮車／導軌互制的動力控制理論（基本磁浮理論＋車體振動控制） 2. 導軌支承沉陷下，EMS 磁浮車的振動反應與控制（評估磁浮間距對支承沉陷之敏銳度） 3. 地震下，EDS 磁浮車通過懸吊導軌之反應控制（LQR+PID 控制器抑制磁浮車反應） Successful demonstration line of commercial maglev (magnetically levitated) transport in Shanghai (2002) marked a starting milestone of toward more efficient and environmental-friendly guided ground transportation. In 2005, a low speed maglev route (Tubo Kyuryo Line) was employed to serve the local transport of EXPO 2005 Aichi, Japan. In 2008, an urban transit maglev system (UTM-02) for public use started to operate in Daejeon, Korea. Because of contact-less nature for maglev vehicles running on guideway, maglev transport system possesses several environmental-friendly advantages, such as low noise, less energy consumption, and waste gas discharge. With the recent progress of maglev technology in transport, two kinds of maglev technologies have been developed in practical applications: (1) the electromagnetic suspension (EMS) with attractive mode, in which the EMS system can lift a vehicle up to 8~20mm at any speed by the use of distributed magnets beneath a guide-rail; (2) the electro-dynamic suspension (EDS) with repulsive mode, in which the EDS system takes off a running vehicle above its guide-rail with a large guideway clearance of about 10~15cm when the moving speed exceeds a liftoff speed (100~120km/h). To address the dynamic problem of maglev vehicle/guideway interactions, this research project is proposed to extend a period of three years. In the first year, the main efforts will be focused on the development of fundamental theory and formulation of maglev-vehicle/guideway interaction dynamics and control mechanisms of levitation forces, in which interaction responses of maglev vehicle/guideways system will be carried out using an incremental-iterative procedure. Based on the theoretical framework and computational methodology developed above, the research work in the second year is to evaluate the settlement effect of guideway supports on dynamic response of an EMS maglev vehicle traveling over a series of guideway girders. With a hybrid PID+LQR controller, the interaction response of an EDS maglev train running on a suspended guideway shaken by horizontal earthquakes will be studied in the third year of this three-year research project.
