中低速磁悬浮列车五单元转向架曲线通过研究

Study on Curve Negotiation of 5 Units Bogie of Mid-to-low Speed Maglev Vehicle

以五单元转向架磁悬浮列车为例,对磁悬浮列车曲线通过时的运动学规律进行了研究,分析了磁悬浮列车转向架的几何结构和转弯时的运动关系,推导了基于磁导向力平衡假设的磁悬浮列车曲线通过的几何关系的数学表达式,并给出了工程应用的近似计算公式。

In the light of the maglev vehicle with 5 units bogie, the kinematics principle of maglev vehicles during curve negotiation is investigated. The geometrical structure of the bogie of maglev vehicle is analyzed along with its motions during curve negotiation. The mathematical expression of geometrical relation is deduced on the basis of the assumption of electro-magnetic guidance force equilibrium. Also given is the approximate formula for engineering applications.
