三大件转向架的优化——无交叉杆或连杆的库仑减振车辆的最佳性能设计方法

The Optimized Three Piece Bogie——A Design Method for Maximum Performance of Coulomb-Damped Vehicles without Braces or Linkages

论述了三大件库仑减振转向架悬挂装置的设计方法,在不采用轴箱剪切垫、交叉杆和连杆的前提下,实现了转向架横向和垂向的最大稳定性能以及轮轨之间的最小磨耗。该方法证明可通过设计悬挂和减振部件,既提高抗菱刚度,又优化库仑垂向减振性能,从而不需采用辅助的稳定和交叉支撑装置。

This paper describes an objective method for the design of three-piece coulomb damped bogie suspensions to provide maximum lateral and vertical stability, and minimum wheel and rail wear without the use of shear plates, braces, or linkages. The method demonstrates that the suspension and damping components can be designed to simultaneously provide sufficiently high warp resistance with optimum vertical coulomb damping in order to eliminate the need for supplemental stabilization and bracing devices.
