摘　　要：结合青城山磁浮列车示范线工程,开展低速磁浮车辆动态曲线通过性能研究。建立35个自由度的磁浮车辆空间模型,考虑主动电磁悬浮与导向,仿真分析低速磁浮车辆曲线通过动态响应。计算结果表明,低速磁浮车辆可以60km·h-1速度安全通过半径300m的曲线,以90km·h-1速度平顺通过半径1100m的无超高曲线。低速磁浮车辆小半径曲线通过能力主要受车/轨横向间隙的影响,大半径曲线可不设置超高,但最大通过速度主要受乘坐舒适性的制约。The curve negotiation performance of low-speed maglev vehicle were studied based on Qingcheng Mountain maglev demonstration line. A 35 degree-of-freedom curving model of the maglev vehicle was developed to simulate its dynamic curving behaviors considering the feedback control of electromagnetic suspension and guidance. Numerical results show that low-speed maglev vehicle can negotiate safely the 300 m radius curve at a speed of 60 km&middoth-1, and can pass through smoothly the 1100 m radius curve without superelevation at a speed of 90 km&middoth-1. It is concluded that the curve negotiation performance of low-speed maglev vehicle on small radius curves are mainly affected by the lateral mechanical clearances between maglev vehicle and guide rail. Moreover, the superelevation is not necessary for the large radius curve and the maximum curving speed is restricted by the ride comfort.
