摘　　要：分析了涡流制动的原理，引入了“迎流的”（ｕｐｗｉｎｄ）有限元法计算具有速度矢量项的有限元方程，根据电磁力的麦克斯韦定理计算了列车的制动力，结果表明：轨道涡流制动的制动力在列车低速区随列车速度的提高而增大，在列车高速区则随列车速度的提高而下降，在某一列车速度下。The principle of eddy current braking is analysed. An 'upwind' finite element method is introduced in order to calculate the finite element equation with velocity vector. The calculation of braking force is completed according to the Maxwell's theorem of electromegnetic force. It is indicated that the braking force increases in the low speed range when the speed of the vehicle is increased, while in the high speed range it decreases when the speed of the vehicle is increased. The braking force reaches maximum when the speed of the vehicle equals some value.
