Magnetism is also used to lift the train off the guideway to reduce friction,diminishing wear and tear where the train meets the guideway.The special coils aboard the train and on the guideway repel each other, making the train float.This repulsion force is so strong that it can lift a moving 10,000-kilogram train 10 centimeters off the guideway.The braking action is accomplished by changing the polarity of the train coils relative to those of the guideway coils, reversing their relationship from one of attraction between two unlike poles to one of repulsion between two like poles.
Japanese National Railway System engineers believe the new maglev trains will be an improvement over the Shinkansen,Not only wll the maglev be faster than the Bullet,it will
be more comfortable and more reliable as well.Since the maglev rides on a magnetic wave,it has a low noise level and a diminished vibration level.This is an important consideration for the people libing in neighboring areas,particularly in a country with such high population density.Low maintenance is another advantage of the maglev train because of the fact that the maglev has no moving his factor virtually eliminates guideway wear and tear and prevents costly break-downs.In addition,much less time will be spent on equipment inspection,track repair,and parts replacement.
The Japanese are still conducting test runs of new prototype maglev train and have been running ummanned maglev prototypes since 1972.In1997.a renite-controlled maglev in Miyazaki,Japan,set a world speed record of 341 miles per hour.

磁也可以用于使火车升离导轨,以减少摩擦,减少磨损当火车摩擦导轨.列车和导轨上的特殊线圈互斥对方,使列车悬浮.斥力是如此强大的,它可以解除移动10000公斤重的列车10厘米升离导轨.刹车制动是通过改变极性的列车线圈相对于该导轨线圈,扭转了他们的关系.
日本全国铁路系统工程师相信新的磁浮列车,将可改善新干线,而不是只比子弹头更快,它会更舒服和更可靠的,因为磁浮靠的是磁力波,它具有低噪声水平,并减少了振动.这是一个重要的考虑因素,特别是考虑周边地区的人们,尤其是在几个高人口密度亚洲国家.低维修率是磁浮列车的另外一个好处,因为这一事实,除磁悬浮没有任何其他的因素几乎完全消除了导轨磨损和防止昂贵的抛锚.此外,少得多的时间将花在设备检查,轨道维修与零件更换.
日本仍在进行试运行的新样机的磁悬浮列车,并已运行磁浮原型自从1972年.在1997年磁悬浮技术在日本宫崎县的世界速度纪录达到了341英里每小时.
大体意思可以参照下面
磁悬浮列车利用“同性相斥,异性相吸”的原理,让磁铁具有抗拒地心引力的能力,使车体完全脱离轨道,悬浮在距离轨道约1厘米处,腾空行驶,创造了近乎“零高度”空间飞行的奇迹.
世界第一条磁悬浮列车示范运营线——上海磁悬浮列车,建成后,从浦东龙阳路站到浦东国际机场,三十多公里只需6~7分钟.
上海磁悬浮列车是“常导磁吸型”(简称“常导型”)磁悬浮列车.是利用“异性相吸”原理设计,是一种吸力悬浮系统,利用安装在列车两侧转向架上的悬浮电磁铁,和铺设在轨道上的磁铁,在磁场作用下产生的吸力是车辆浮起来.
列车底部及两侧转向架的顶部安装电磁铁,在“工”字轨的上方和上臂部分的下方分别设反作用板和感应钢板,控制电磁铁的电流使电磁铁和轨道间保持1厘米的间隙,让转向架和列车间的吸引力与列车重力相互平衡,利用磁铁吸引力将列车浮起1厘米左右,使列车悬浮在轨道上运行.这必须精确控制电磁铁的电流.
悬浮列车的驱动和同步直线电动机原理一模一样.通俗说,在位于轨道两侧的线圈里流动的交流电,能将线圈变成电磁体,由于它于列车上的电磁体的相互作用,使列车开动.
列车头部的电磁体N极被安装在靠前一点的轨道上的电磁体S极所吸引,同时又被安装在轨道上稍后一点的电磁体N极所排斥.列车前进时,线圈里流动的电流方向就反过来,即原来的S极变成N极,N极变成S极.循环交替,列车就向前奔驰.
稳定性由导向系统来控制.“常导型磁吸式”导向系统,是在列车侧面安装一组专门用于导向的电磁铁.列车发生左右偏移时,列车上的导向电磁铁与导向轨的侧面相互作用,产生排斥力,使车辆恢复正常位置.列车如运行在曲线或坡道上时,控制系统通过对导向磁铁中的电流进行控制,达到控制运行目的.
