迫导向机构对中低速磁浮车辆曲线通过性能的影响

Influence of Forced Guiding Mechanism on Medium and Low Speed Maglev Vehicle Curve Passing Performance

为研究迫导向机构对中低速磁浮车辆的影响,建立了精细化的四模块、五模块中低速磁浮车辆动力学模型。对比分析了四模块、五模块中低速磁浮车辆通过曲线线路时有、无迫导向机构的动态响应差异,以及迫导向机构在不同未平衡加速度下的作用机制。结果表明,当未平衡加速度较大时,迫导向机构发挥导向作用;反之,迫导向机构发挥抗导向反作用。抗导向时,四模块中低速磁浮车辆迫导向机构转臂受力较大时,可采取中间移动滑台拆分的方式降低受力。在横风等强激扰下,迫导向机构对中低速磁浮车辆曲线通过性能具有积极意义。

To study the influence of forced guiding mechanism on medium and low speed maglev vehicle,the refined dynamic models of both 4-module and 5-module medium and low speed maglev vehicles are established.The dynamic response differences when 4-module and 5-module medium and low speed maglev vehicles passing curve routes with or without the forced guiding mechanism are comparatively analyzed,the action mechanism of the forced guiding mechanism under different unbalanced accelerations is also studied.Results show that when the unbalanced acceleration is large,the forced guiding mechanism plays a guiding role;in the opposite condition,the forced guiding mechanism plays an anti-guiding reaction.When the anti-guiding is functioning,the rotating arm of the forced guiding mechanism in 4-module medium and low speed maglev vehicle is subjected to a greater force,then the middle mobile slide can be split to reduce the force.Under strong disturbances such as crosswinds,the forced guiding mechanism has positive significance for the curve passing performance of medium and low speed maglev vehicles.
