摘　　要：为合理选择轴箱内置转向架车辆抗侧滚刚度,建立某地铁车辆动力学模型,分析一系、二系垂向刚度和抗侧滚扭杆刚度对车辆运行平稳性、扭曲线路通过和抗侧滚性能的影响。研究结果表明:一系垂向刚度和抗侧滚扭杆刚度对车体的平稳性指标影响较小,而二系垂向刚度对车体垂向振动的影响较为明显。一系、二系垂向刚度和抗侧滚扭杆刚度较大时,虽然车辆具有优秀的抗侧滚能力,但是不利于列车通过扭曲线路。因此车辆抗侧滚刚度取值既要满足轴箱内置转向架车辆抑制侧滚的需求,也要具备良好的适应线路扭曲的能力。In order to reasonably select the anti-rolling stiffness of the vehicle with built-in bogie in the axle box,a dynamic model of a metro vehicle is established,and the effects of the primary and secondary vertical stiffness and stiffness of anti rolling bar on the vehicle running stability,twisted line passing and anti-rolling performance are analyzed.The results show that the primary vertical stiffness and stiffness of anti-rolling bar have little influence on the stability index of the car body,while the secondary vertical stiffness has a more obvious influence over the vertical vibration of the car body.When the primary and secondary vertical stiffness and stiffness of anti-rolling bar are large,it is not conducive to the train passing through the twisted line despite the excellent anti-rolling ability of the vehicle.Therefore,the value of vehicle anti-rolling stiffness should be within a reasonable range,which not only meets the needs of vehicle with built-in bogie in axle box to suppress rolling,but also ensures good ability of adapting to line distortion.
