以国家863项目——“车辆涡流制动技术研究”中磁悬浮涡流制动试验台为研究对象,着重研究涡流制动过程的电磁机理。以Maxwell方程为出发点,根据推导出来的轨道涡流制动特性方程,分析了速度、励磁电流和气隙对制动力的影响,并用试验台的试验数据对方程进行了验证。
Taking the national 863 project - “Research on Vehicle Eddy Current Braking Technology” as the research object, the electromagnetic mechanism of the eddy current braking process is mainly studied. Based on the Maxwell equation, the influence of the speed, excitation current and air gap on the braking force is analyzed based on the derived orbital vortex braking characteristic equation. The equation is validated by the experimental data of the test rig.
