中低速磁浮列车走行部迫导向机构转向特性研究

Research on Turning Performance of Forced Guiding Structure of Medium and Low Speed Maglev Train

现有中低速磁浮列车均采用五悬浮架布置形式,在车体与悬浮架之间设置了磁浮车辆特有的迫导向机构。针对现有迫导向机构转向性能不足导致列车无法顺利通过曲线的问题,开展迫导向机构转向特性研究,通过运动学分析计算和受力分析确定迫导向机构的关键尺寸参数,仿真分析对参数进行优化,经试验验证,车辆转向特性良好。

The existing medium and low speed maglev trains are all arranged in the form of five suspending bogies,and a forced guiding structure to the maglev vehicle is set between the car body and the suspending bogies.Aiming at the problem that the train cannot pass the curve smoothly due to insufficient steering performance of the existing forced guiding structure,this paper studies the steering characteristics of the forced guiding structure,the key size parameters of the forced guiding structure are determined by kinematics analysis and force analysis,and then parameters are optimized by simulation analysis.The vehicle steering characteristics are verified by experiments.
