Experimental Equipments for the Magnetic Leviation

利用普通磁体和超导磁体制作了电动系统磁悬浮悬浮实验装置。通过使用这些设备，我们测量了电磁力与车辆垂直位移或速度的关系。我们计算了我们制造的设备所产生的电磁力。计算结果与实测结果吻合。这不仅表明我们可以建立一个仿真模型来估计设备的性能，而且可以证明悬浮力和阻力的基本特性。结合设备制造的基本特性，采用两种方法对车辆的振动进行了抑制。一是控制二次悬浮，二是控制电磁铁产生的磁通。明确了两种方法，并明确了它们的特点。在列车4个转向架上有3节车厢的情况下，对电动系统磁悬浮车辆的平顺性进行了评价，把握了优化列车被动结构时控制二次悬架对平顺性的改善。

We made experimental equipments for the magnetic levitation (maglev) suspension of electric dynamic systems using normal magnets or super-conductive magnets. By using the equipments, we measured electromagnetic forces versus vertical displacement or velocity of the vehicle.We calculated electromagnetic forces which would be generated in the equipments we made. The results of calculation and measurement coincided. This indicates not only that we could construct a simulation model which can estimate the property of the equipments, but also that we could certificate the basic characteristic of levitation force and drag force.By considering the basic characteristic obtained by making the equipments, we tried to restrain the vibration on the vehicle by two method. One is to control secondary suspension and the other is to control magnetic flux caused by electromagnet. We clarified two method and made the characteristics of them clear.We evaluated the ride quality of magnetic levitation vehicle of electric dynamic systems assuming that trains have 3 cars on 4 bogies, and grasped improvement of ride quality when the secondary suspension is controlled of passive structure of the train is optimized.
