摘要
侧风作用是影响高速磁浮系统动力设计的重要因素之一.为获得侧风作用下高速磁浮列车-轨道梁耦合振动响应,首先,建立了风-静悬磁浮列车-轨道梁(WSMG)和风-移动磁浮列车-轨道梁(WMMG)空间耦合分析模型.然后,通过风洞试验对磁浮车辆的气动特性进行测试.磁浮列车的控制系统采用比例-积分-微分(PID)控制器和加速度反馈相结合的比例-积分-微分-加速度(PIDA)控制算法进行调控.最后,分析了平均风、脉动风、风速和车速对磁浮系统动力响应的影响.结果表明:PIDA控制算法可以消除侧风引起的磁浮间隙稳态误差,并减小大约40%的车体横向位移;均匀风只改变列车的平衡位置,脉动风和轨道不平整是引起磁浮列车-轨道系统振动的主要原因;风速对车辆的横向振动的影响更为敏感,当风速超过30 m/s时,高速磁浮列车应停止运行.
Abstract
Exposed to crosswinds,dynamic response of the train and the guideway are the important aspects in the design of the high-speed maglev transit system.Firstly,the aerodynamic characteristics of a maglev vehicle were tested through a wind tunnel test.The proportional-integral-derivative-acceleration(PIDA)control algorithm,which combines a proportional-integral-derivative(PID)controller and acceleration feedback,was used to adjust the levitation and guidance control system of the maglev train.The spatial analysis model of the wind-static suspension-maglev train-guideway(WSMG)system and wind-moved maglev train-guideway(WMMG)were established.Subsequently,the influences of average wind,fluctuating wind,wind speeds,and vehicle speeds on the dynamic response of the maglev system were analyzed.The results indicate that the PIDA controller can eliminate the steady-state error of the magnetic gap caused by crosswinds.Compared with the PDA controller,the PIDA controller can reduce approximately 40%of the lateral displacement of the vehicle body.The average wind only changes the equilibrium position of the train,and the fluctuating winds and track irregularities are the significant cause for the vibration of the maglev train-guideway system.The lateral vibration of the vehicle is more sensitive to the wind velocity.The high-speed maglev train should stop running when the wind speed exceeds 30 m/s.
