The thesis analyzed the present transferring status between pudong airport and shanghai " s incity. through forecasting the long - dated flux of pudong airport and the area near it and combining the planning scheme of shanghai urban rapid mass transit, the thesis learned the helpful experience of the traffic organization in typical airport abroad and used the scientific analyzing model of public traffic flux forecasting to put forward some reasonable suggestion of the bottleneck question between pudong airport and incity : the one is to use the present no. 2 subway as the future airtrain to take on the most part of the flux and meantime present the concept of feeder efficiency to quantitative analyze the choice of feeder station ; the other is to set up cat ( city air terminal ) to convenient the passenger to come airport rapidly and economically in order to lessen the pressure of the traffic and improve the whole service quantity of civil aviation transportation
本文分析了浦東機場與市內目前的換乘現狀,從預測浦東機場及緊鄰空港區域中遠期的客流量入手,結合上海市政府快速軌道交通的規劃方案,並且學習境外典型機場交通組織的有益經驗,利用規劃中的公交客流預測等科學分析模型,對浦東機場與市中心的軌道交通銜接提出了合理的建議:一是利用目前的地鐵二號線作為航空軌道共享線來承擔大部分進出空港的客流,並且給出了以接運效率最大化為目標函數的接運公交軌道站點比選模型;二是在市中心設立城市航站樓以方便旅客快速、經濟地到達機場,從而減少道路交通壓力,提高航空運輸的整體服務質量。The subject of this thesis is to study ironless moving coil linear permanent magnet synchronous motor and the major works in this thesis are summarized as follows : 1 ) two analytical formulas are derived by concentrated current method and distributed current method to determine the magnetic field due to pm, based on the current model of pm. besides, two method ( magnetic charge method and solution by laplace equation method ) are also introduced with comparing their advantages and disadvantages. then the effects of the motor parameters on the flux distribution are discussed
本文對空芯動圈式直線同步電動機進行了深入細致的研究,內容包括: ( 1 )採用電流模型推導出兩種計算永磁磁極二維氣隙磁場的解析公式(集中電流法、分佈電流法) ,同時介紹了兩種永磁電機氣隙磁場計算方法(磁荷法,直接求解拉氏方程法) ,分析各種方法的優缺點,討論電機參數對氣隙磁密的影響; ( 2 )介紹了單層同心繞組的布置方式,根據安培定律推導出空芯動圈式直線永磁同步電動機的靜推力計算公式,分析靜態力?位移特性; ( 3 )建立空芯動圈式直線永磁同步電動機動態模擬模型,模擬不同驅動方式下電動機起動、穩態運行時電磁力、速度、位移的變化情況。
