One of the key technologies in high speed maglev trains is the design and control of linear synchronous motor ( lsm ) . this paper investigates the basic theories and some characteristics of lsm 高速磁悬浮列车的关键技术之一是列车用直线同步电机的设计与控制，本论文对直线同步电机的基本理论和一些特性进行了分析和研究。
Last , the brake control system of the low - speed maglev train which has been set up is simulated , then the simulation result is analyzed to test and compare the effect and performance of the two different control methods 最后,本文对低速磁浮列车的制动控制系统进行了仿真,分析了仿真结果,检验和比较了各种控制方法的效果和特性。
The extremely low noise level achieved by the maglev technology , as demonstrated by the operation of maglev trains in shanghai , may command an advantage in areas with high population density and should also be taken into account 上海磁悬浮列车使用后，确实噪音量极低，在人口密集的环境下，可能占有优势，亦是应考虑的优点之一。
The principle of the maglev train is quite different from the tranditinal train . because there is no michanical friction between the train and the rail , the communication via the loop of rail and wheels is unable to use 磁浮列车在工作原理和运行方式等方面不同于传统的轮轨列车,车辆和轨道没有机械接触,无法由车轮和导轨组成回路来完成数据通信。
If the maglev technology is adopted , a new and separate rail corridor will have to be built for use by maglev trains , and it is anticipated that the construction time will be longer than that under the wheel - on - track option 如采纳磁悬浮技术方案，则须修建一条全新、独立的铁路通道以供磁悬浮列车使用，预计项目的建造期会较采纳轮轨技术方案为长。
The conclusion of the paper is that the shanghai demonstrable line of the maglev train is reasonable in technology and possible in economics . the participation of guangda bank in the project loan is also practicable 最后得出的结论是，上海市磁悬浮列车示范运营线项目不仅在技术上是可行的，在经济上也是合理的，光大银行参与该项目的贷款也是可行的。
Test result proved that the computer - controlled brake system is faster , more stable and dependable , computer - controlled brake system is new break - through in the mechanical brake system of maglev train 试验证明,引入计算机控制的制动系统不仅提高了制动的快速性,稳定性和可靠性也有很大提高,计算机制动系统是计算机控制在我校磁浮列车机械制动中的新突破。
The train - ground communication system plays a very important role in the maglev train . an efficient and reliable train - ground communication system is the key to insure the safty of the train and the smooth transimision of commands and attempts 车地通信系统在磁浮列车运行中发挥着重要作用,可靠而高效的通信系统是保证列车指挥调度通畅、运行安全可靠的关键。
