摘　　要：为了分析电磁缓速器对客车制动性能的影响,简化建立客车传动系的键合图,再将键合图转化为方框图,然后用Matlab/Simulink工具中的模块库建立了装有电磁缓速器的客车制动性能仿真模型并进行了仿真。仿真结果表明,电磁缓速器减轻了主制动器的工作负担,有效地提高客车的制动性能,所建仿真模型可以用于指导客车电磁缓速器的优化设计。To analyze the influence on the braking performance of the city bus with the use of eddy current brake,the bus powertrain is simplified and shown with power bond graph,and the power bond graph is transformed into block diagram,then the simulation model of brake performance of the city bus equipped with eddy current brake was established with module library in Matlab/Simulink.The results show that eddy current brake is available to reduce the buden of the brake system and to enhance the brake performance of the city bus,the simulation model can be used in the direction of optimum design of Eddy Current Brake.
