本文分析了转向架轴箱定位装置的设计对车辆运行特性的影响,论证了采用无磨耗的弹性轴箱定位装置的重要意义,研究表明,适当选择和匹配其纵向和横向定位刚度可以获得较低的蛇行运动频率和较高的减振阻尼。本文还分析了轴箱定位装置的结构误差(例如轮对左右轮径差、转向架左右固定轴距差和构架对角线差等)对轮缘磨耗的不利影响,研究表明,结构误差的影响程度与轴箱定位装置的设计有关。最后,通过实例计算对上述研究结果作了进一步论证,并且提出应对转向架的制造和组装精度予以严格控制。
This paper analyzes the influence of the design of the bogie axle positioning device on the running characteristics of the vehicle, and demonstrates the importance of using a wear-free elastic axle box positioning device. The research shows that proper selection and matching of longitudinal and lateral positioning stiffness can obtain a lower The snake frequency and high damping damping. The paper also analyzes the structural errors of the axle box positioning device (such as the difference of wheel diameter on the left and right, the fixed wheelbase difference between the left and right bogies, and the diagonal difference of the frame) on the wheel rim wear. The results show that the influence of structural error Degree and axle box positioning device design. Finally, the results of the above studies are further demonstrated by examples and the strict control over the manufacturing and assembly accuracy of bogies should be put forward.
