铁道机车运用与维护专业英语（第2版）课件：磁悬浮列车

磁悬浮列车Maglevtrain磁悬浮是利用磁力来移动车辆而不接触地面的方法。利用磁铁产生升力和推进力，从而减少摩擦，实现非常高的速度。Maglevisatransportmethodthatusesmagneticlevitationtomovevehicleswithoutmakingcontactwiththeground.Withmaglev,avehicletravelsalongaguidewayusingmagnetstocreatebothliftandpropulsion,therebyreducingfrictionbyagreatextentandallowingveryhighspeeds.Maglevtrain什么是磁悬浮列车/Whatisamaglevtrain01磁悬浮列车的种类/Typesofmaglevtrain0203相关术语/Currentterms04中国磁悬浮列车未来展望/Futureprospectsofmaglevtrain什么是磁悬浮列车Whatisamaglevtrain01磁悬浮列车/Mglevtrain

磁悬浮列车是一种没有车轮的陆上无接触式有轨交通工具，其原理是：利用常导或超导电磁铁与感应磁场之间产生相互吸引或排斥力，使列车“悬浮”在轨道上面或下面，作无摩擦的运行。Maglevtrainsarenon-contactrailtransportonlandwithoutwheels,Theprincipleis:theuseofnormalconductivityorsuperconductingelectromagnetandinducedmagneticfieldbetweenthemutualattraction.Orrepulsiveforce,whichcausesthetrainto“levitate”aboveorbelowthetrackforfrictionlessmovement.Maglevtrain磁悬浮列车长沙磁悬浮列车Changshamaglevtrain磁悬浮列车/Mglevtrain

磁悬浮列车推进系统最关键的技术是把旋转电机展开成直线电机。它的基本构成和作用原理与普通旋转电机类似，展开以后，其传动方式也就由旋转运动变为直线运动。

没有畏难，没有放弃。邓江明不断尝试设计方案，最终确定先把1.0版直线电机前后200毫米的空间用完以提高其同步速度，之后再对电机内部绕组结构进行优化。

第一次试浮，悬浮系统报出故障。30多人断电校线，反复试验不下10次，历时两天两晚才浮起来。

常导型（EMS），在车体的两侧转向架上的底部安装电磁铁，与位于电磁铁上方的导轨相吸引而使车辆浮起。悬浮的气隙较小，一般为10mm左右。常导型高速磁悬浮列车的速度可达400~500km／h。

无论是轮轨铁路还是磁悬浮铁路，当车辆处于开放空间大气环境下以超过160km/h速度运行时，均要面临巨大的空气阻力和噪声问题，从而在商业运营上带来经济性和环保性的挑战。因此，为获得更高的经济运行速度，在利用悬浮技术减少车轨摩擦、振动的基础上，再构建低真空运行环境以减小空气阻力和噪声是未来更高速度轨道交通技术的重要发展方向。Nomatterwheel-railrailwayormaglevrailway,whenthevehicleisrunningataspeedofmorethan160km/hintheopenspaceatmosphericenvironment,ithastofacehugeairresistanceandnoiseproblems,whichbringseconomicandenvironmentalchallengesincommercialoperation.Therefore,inordertoobtainahighereconomicoperatingspeed,onthebas
