| 摘 要： | 以德国Transrapid磁浮列车系统为基础,采用现有的磁浮车辆垂向模型,建立了有限元轨道梁模型、磁浮车轨垂向耦合系统模型及其振动微分方程.在此基础上,针对德国在上海的磁浮项目,主要就轨道梁的型式(简支和连续)、支承刚度及轨面不平顺波长对磁浮车辆-轨道耦合系统动力响应的影响等进行了分析.

| Abstract: | Based on the Maglev train system of Germany (Transrapid), a finite element model of the elevated-beam guideway, a vertical coupling system model of vehicle/guideway and their dynamic differential equations are set up. The present vertical maglev vehicle model is used. The present analysis is focused on the factors which influence the dynamic response of the maglev vehicle/guideway coupling system, such as the elevated-beam type (freely supported beam or continuous beam) of the guideway, the supporting stiffness, the wavelength of irregularity and so on. |
