摘　　要：线路匹配性能是指高速轨道车辆与不同线型缓和曲线之间相互动力作用所决定的匹配性能。为了研究高速磁浮车辆的线路匹配性能，进行了1列3车车组曲线通过性能仿真分析。与轮轨导向不同，高速磁浮导向是在主动导向控制下电磁导向力使整个走行部准确地沿轨道中心线无接触悬浮运行。为了消除传统曲线计算公式存在的误差以满足磁浮线路的高精度和连续光滑要求，利用基于样条函数技术的新方法设计了如下两种线形缓和曲线：正弦形和圆整基本线形。1列3车车组的曲线通过性能仿真对比表明：根据高速磁浮导向原理，当有超高限速曲线通过时，正弦形缓和曲线具有优越的线路匹配性能；而圆整基本线形（仍属于三次抛物线）则不具备良好的线路匹配性能；当无超高曲线通过时两者匹配性能相当。Curve - matching performance is the matching performance determined by the dynamic interactions between high- speed railway vehicles and various- type transional curves. In order to investigate the curve - matching performance of high - speed MagLev vehicle, the simulation analysis of three - vehicle trainset＇ s curve negociation performance had been done. In contrast to rail - wheel guidance, high - speed MagLev guidance is that under active guiding control the electro- magnetic guiding forces keep the full working assembly moving precisely in the railway centerline. For eliminating the coordinate calculating- error in the old curve formula and satisfying the requirements of MagLev curve＇ s high- precision and smoothness, the two- type following curves are designed with the new methodology based on sphne function technology： sine - type and rounded basic - type.The curve negociation performance simulations of three - vehicle trainset show that according to the guiding principle of high - speed MagLev, when running on the velocity- limited canted curve, the sine - type transitional curves have the excellent matching performance; but the rounded basic - type curves （which belong to the cubic parabola） do not have the required matching performance; when running on the uncanted curves the both have the equivalent matching performance.
