摘要
针对地铁列车在轮轨低黏着接触状态下车轮打滑问题,提出一种基于电磁力作用的地铁列车防滑控制策略.基于车辆-轨道耦合动力学理论,建立地铁列车-板式轨道耦合动力学模型,模型中考虑非线性轮轨相互作用关系和磁轨增黏装置的防滑控制策略.通过数值仿真分析低黏着接触状态和牵引/制动工况下轮轨动态作用和防滑控制效果.研究结果表明,在低黏着接触条件下车轮易发生打滑现象.采用基于电磁力作用的防滑控制策略可增加轮轨垂向力,进而增大轮轨蠕滑力,同时阻止车轮打滑现象;与传统的防滑控制策略相比,采用考虑基于电磁力作用的防滑控制策略时,在轮轨低黏着接触区段可提高地铁车轮的牵引/制动效率.
Abstract
A novel anti-slip control strategy considering electromagnetic effort is proposed to enhance the adhesion level and prevent slipping problems of metro wheels under low-adhesion friction conditions.To this end,a metro train-slab track coupled dynamics model is established,in which the non-linear wheel/rail interactions and the advanced anti-slip control module are treated.The wheel/rail interactions and anti-slip controlling effect under complex wheel/rail friction conditions and traction/braking operations are numerically investigated.The simulation results indicate that the powered wheelset is prone to slip under low-adhesion conditions.The proposed anti-slip controller can improve wheel/rail adhesion level and restrain wheelset slipping phenomenons with the increasing wheel/rail vertical forces.Moreover,the employed anti-slip controller improves traction/braking efficiency compared to the traditional one.
