摘要
评述了磁浮车辆/轨道系统动力学建模、数值求解及动力响应分析与动力性能评价等方面的研究进展。随着磁浮列车技术逐步成熟,磁浮车辆/轨道系统动力学建模越来越细致,动力学仿真主要开展了车/桥垂向耦合作用研究、车辆曲线通过性能研究和车辆/轨道系统随机振动响应研究。为了更为真实地模拟磁浮列车系统动力响应,今后需要建立考虑磁转向架结构、悬浮导向控制系统、直线电动机和空气动力作用的耦合大系统动力学模型,寻找高效求解磁浮大系统非线性时变微分方程的数值方法,开展磁浮列车系统动力学参数优化研究、磁浮列车纵向动力学研究以及动力学仿真试验验证,并确立一套磁浮列车系统动力学性能评价标准。
A state-of-the-art review on maglev vehicle/guideway system dynamics including modeling, numerical simulation and dynamic performance evaluation is presented. As maglev train technology advanced towards the level of commercial application, dynamic simulations of maglev vehicle/guideway system used more detail and complex coupling models. And great progress is made in studies on the maglev vehicle/guideway vertical interaction, curve negotiation and randomvibration. In the future, the large system model considering the bogie structure, the levitation and guidance control system, aerodynamic effect and linear motor force should be established to simulate truly dynamic behaviors of maglev train system, which make it necessary to explore new high-efficient numerical method solving the nonlinear time-varied differential equations of maglev vehicle/guideway controller system. Furthermore, studies on the experimental verifications of dynamic model and simulation, the maglev train longitudinal dynamics, the dynamic optimization of maglev train system, and the specifications for evaluating dynamic performances should be carried out as soon as possible.
