摘　　要：根据120 km/h A型地铁车辆及实际运营线路特点,文章从车辆和轨道相互作用的角度,运用车辆-轨道耦合动力学模型及理论,借助SIMPACK动力学分析软件,分析轨道的整体刚度和阻尼、地铁车辆的悬挂参数对轮轨横向动力作用的影响规律,据此提出实现该型地铁车辆的轮轨横向低动力的措施。结果表明,合理选择轨道的整体刚度和阻尼及地铁车辆的悬挂参数,能有效地降低轮轨横向力,减少轮轨磨耗。Based on the features of 120 km/h type A metro vehicle and subway lines,considering the vehicle and track interaction,using the theory of the vehicle-rail coupling dynamics model,the influence law of the integral rigidity and damping of track,and the suspension parameters of metro vehicle to lateral wheel-rail interaction is analyzed by SIMPACK dynamics software. The measures to realize the lateral wheel-rail hypokinesis of the metro vehicle is put forward. The results show that a reasonable choice of parameters for the integral rigidity and damping of track,and the suspension parameters of metro vehicle,can effectively reduce the lateral wheel-rail interaction and decrease the wheel-rail wear.
