摘要
为研究时速600公里高速磁浮线路平面参数合理取值,本文建立了考虑部件弹性、磁力非线性、控制系统时滞效应等因素的精细化车辆系统动力学仿真模型,并验证了模型的准确性。仿真分析了平面曲线半径和缓和曲线长度对车辆动力学性能的影响,提出了时速600公里高速磁浮平面曲线半径及缓和曲线长度建议值。根据动力学仿真分析结果,综合考虑车辆的悬浮导向稳定性及运行平稳性,建议时速600公里高速磁浮最小平面曲线半径为11000 m,缓和曲线长度为1000 m。
In order to study the reasonable values of the horizontal parameters of high-speed maglev lines with a speed of 600 km/h,this paper established a refined vehicle system dynamics simulation model that took into account factors such as component elasticity,magnetic force nonlinearity,and the time-delay effect of the control system,and verified the accuracy of the model.Through simulation,the influence of the horizontal curve radius and the length of the transition curve on the vehicle's dynamic performance was analyzed,and the recommended values for the horizontal curve radius and the length of the transition curve of high-speed maglev with a speed of 600 km/h were put forward.Based on the results of dynamic simulation analysis and considering the levitation guidance stability and running smoothness of the vehicle comprehensively,it is recommended that the minimum horizontal curve radius for high-speed maglev with a speed of 600 km/h be 11000 m and the length of the transition curve be 1000 m.
