本文论述了在机车车辆工业中，在车辆设计和开发过程中，在研究运行稳定性时，非线性计算和分叉分析的应用。介绍了工业应用中稳定性分析的典型方法，给出了分岔图的计算方法，并研究了车辆/轨道系统的非线性对Hopf分岔类型的影响。讨论了分岔图与安全风险评价及动态行为的关系。
This paper deals with the use of nonlinear calculations and bifurcation analysis when investigating running stability during vehicle design and development in the rolling stock industry. Typical methods used for stability analysis in industrial applications are introduced, computation of bifurcation diagram presented and the influence of nonlinearities of the vehicle/track system on the type of Hopf bifurcation investigated. The relationship between the bifurcation diagram and the assessment of safety risk and the dynamic behaviour is discussed.
