摘要:

将机车作为一个整体系统，用17个自由度描述机车在一般情况下横向平面的空间位置.考虑到一系、二系悬挂装置的弹性支承以及减振器的阻尼特性，建立了四轴转向架式车辆蛇形运动力学模型，列出运动微分方程.用变步长法求出的特征值研究车辆蛇形运动稳定性及机车临界速度，结论为：增大轮对的横向及纵向刚度和阻尼，可以减小转向架和车体的蛇形运动.得出了合理的优化参数，并提出了改进措施：将液压减振器改为电磁液压减振器或蛇形减振器，用锥式弹簧代替原来的柱式弹簧.

Abstract:

Taking the locomotive as a whole system, 17 degrees of freedom are used to describe the spatial position of the locomotive in the transverse plane in general. Considering the elastic support of the suspension device of the first series and the damping characteristics of the shock absorber, the mechanical model of serpentine motion of the four-axis bogie vehicle was established, and the differential equations of motion were listed. The eigenvalues obtained by the variable step method are used to study the serpentine motion stability and the critical speed of the locomotive, and the conclusion is that increasing the lateral and longitudinal stiffness and damping of the wheelset can reduce the serpentine motion of the bogie and the car body. Reasonable optimization parameters were obtained, and improvement measures were proposed: the hydraulic shock absorber was changed to an electromagnetic hydraulic shock absorber or a serpentine shock absorber, and the original column spring was replaced by a cone spring.
