摘要: 中低速磁浮列车每个悬浮模块包含四个电磁铁线圈,一般采用两端线圈串联的方式分别与一个控制器构成悬浮控制回路,称为一、二位连接方式(C12)。为提高磁浮车辆的悬浮性能,改善运行过程中的触轨和悬浮失效等问题,目前大部分研究从优化悬浮控制系统入手。从外部连接出发寻找较优的串接方式,提出一种新型的一、三位连接方式(C13),通过动力学和电磁仿真将两种连接方式进行详细的对比。研究结果表明:在通过相同轨道垂向激励时,一、三位连接方式悬浮架与轨道的最小距离更大,即离轨道更远;用于调整的控制器平均电流更低。所以从安全性和线圈发热考虑,一、三位连接方式优于一、二位。提出一种新型的线圈连接方式,证明了其优越性,可为工程应用提供选择依据。

Abstract: In the medium-low speed maglev vehicle, each levitation module contains four electromagnet coils. Generally, two adjacent coils at the module end in series with one controller, which is called control mode of series connection in the 1st and 2nd coils (C12). In order to enhance the levitation performance and improve the problems such as touching the rail and levitation failure in the process of running, many researches start from levitation control system optimization. The external connection mode is started from, and a new type of control mode of series connection in the 1st and 3rd coils (C13) is proposed. Many detailed comparisons of the two modes are made by dynamic and electromagnetic simulation. When passing through the same rail excitation, the results show that the minimum distance between the levitation frame and the rail in C13 is larger than that in C12, that is, farther from the rail; the average current of the controller in C13 is lower. Therefore, considering the safety and coil overheating, C13 performs better than C12. A new type of coil connection mode is proposed and its superiority is proved, which provides a basis for engineering applications.
