摘要: 以三转向架磁悬浮车为例,对磁悬浮车曲线通过时的运动学规律进行了研究.磁转向架通过曲线时的状 态由磁导向力和几何约束确定.推导了基于磁导向力平衡假设的磁悬浮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.实例计算表明,近似公式计算结果与迭代计算结果相差很小,满足工程设计 的需要.Abstract: By taking three-truck maglev vehicle as an example, the kinematics lawof maglev vehicles on a curved track is investigated. The mathematical expression of geometrical relation negotiating is deduced on the basis of the supposition of electric magnetic guide force equilibrium, and an approximate formula convenient for use in engineering is presented.
