摘要

超导电动悬架列车具有悬浮/制导自稳定性、悬浮间隙大、升阻比高等优点,正成为高速、超高速铁路运输的可行选择。为了给优化控制策略的设计提供依据,本文建立了考虑转向架和车体各方向动力学的SC-EDS列车综合模型。该模型揭示了各变量之间复杂的耦合和反馈关系,这是现有的SC-EDS列车局部模型所不能描述的。给出了不同参数和初始条件下的仿真实例,并进行了讨论,以证明本文模型的潜在用途。

Comprehensive Model Construction and Simulation for Superconducting Electrodynamic Suspension Train
With the advantages of levitation/guidance self-stability, large levitation gap, and high lift-to-drag ratios, superconducting electrodynamic suspension (SC-EDS) train is becoming a viable candidate for the high-speed and ultra-high-speed rail transportation. In order to provide the basis for designing the optimization and control strategy, this paper establishes a comprehensive model for the SC-EDS train, which considers the dynamics of the bogie and car body in all directions. The obtained model reveals the complex coupling and feedback relationships among the variables, which cannot be described by the existing local models of the SC-EDS train. Simulation examples under different parameters and initial conditions are presented and discussed to demonstrate the potential use of the model given in this paper.
