摘要
文章通过对铁路车辆转向架蛇行运动稳定性的分叉进行研究,分析了车辆系统在不同分叉状况下对车辆安全性能的影响。运用中心流形方法研究6自由度的车辆转向架,考虑轮轨接触几何关系和轮轨相互作用力的非线性,抗蛇行减振器的非线性,其余悬挂参数为线性。对系统稳定性进行判定,为以后车辆的设计提供了一个较好的方法。
Based on the Hunting Stability of Railway Bogie to study the bifurcation analysis of the vehicle system at different bifurcation conditions of the vehicl＇e safety performance.Study the use of center manifold Bogie 6 degrees of freedom,consider the wheel-rail contact geometry and the nonlinear interaction force between wheel and rail, the nonlinear yaw damper, and the remaining suspension parameters are linear.Determine the stability of the system for future vehicles designed to provide a better way.
