车辆系统的非线性动力学研究进展

文章对非线性动力学在车辆系统运行性能分析与优化过程中的应用作了简单的介绍。从非线性因素对轮对、转向架、机车、货车、高速客车在运行过程中的影响分别结合传统算法和新的算法作了分析,并提出了一些相应的控制措施。对于对称系统和不对称系统分别作出了分岔图,并用“合成分岔图”法作了分析。考虑非线性因素对于确定车辆的线性和非线性速度提出了新的方法。

In this paper,the Nonlinear Dynamics in vehicle system performance analysis and optimization of the process is introduced briefly.Nonlinear factors,truck,motorcycles,trucks,high speed passenger influence wheel during operation for each combination of traditional algorithms and new algorithms are analyzed.This paper puts forward some corresponding control measures.For symmetric and asymmetric systems,system bifurcation diagrams are made,and an analysis were made using the"synthetic bifurcation diagram"method.Thus,taking into consideration nonlinear factors,this paper proposes new methods for determining the linear and nonlinear speeds of the vehicle.
