摘要: 车轮作为列车走行部件中重要核心部件之一，轮轨相关作用力将直接影响车辆行驶性能和乘客乘坐舒适性，以CRH380为对象，建立了车辆轨道耦合动力学模型，通过仿真分析了车轮扁疤对转向架系统振动特征的影响，结果表明：当轮对车轮出现扁疤缺陷时，扁疤轮对轴箱横向加速度有效值为正常轮对轴箱横向加速度有效值的1.35倍；相同车速下，随着扁疤长度的增加，轴箱横向加速度有效值逐渐增加；不同长度的扁疤引起的轴箱横向振动加速度有效值随车速变化均呈现先增加后减小再增加的趋势；相同车速下，随着扁疤长度的增加，轴箱垂向加速度有效值逐渐增加；不同长度的扁疤引起的轴箱垂向振动加速度有效值均随车速增加而增大。
Abstract: As one of the important core components of train running parts, the wheel rail related force will directly affect the vehicle running performance and passenger riding comfort. Taking CRH380 as the object, the vehicle track coupling dynamic model is established. The influence of wheel flat scar on the vibration characteristics of bogie system is analyzed through simulation. The results show that when the wheel set wheel has flat scar defect, the effective value of transverse acceleration of axle box of flat wheel set is 1.35 times of that of normal wheel set; at the same speed, the effective value of axle box lateral acceleration increases gradually with the increase of flat scar length; the effective value of axle box transverse vibration acceleration caused by flat scar of different length increases first, then decreases and then increases with the change of vehicle speed. At the same speed, the effective value of vertical acceleration of axle box increases gradually with the increase of flat scar length; the effective value of vertical vibration acceleration of axle box caused by flat scar of different length increases with the increase of vehicle speed.
