| 摘 要： | 为了揭示二次交通事故的演变特性,预防二次交通事故的发生,在描述Duffing振子模型的基础上,分析二次交通事故的混沌特性,并建立混沌模型.在仿真环境下,改变模型参数值,得到系统出现周期振荡状态和混沌状态的系统结构条件,并绘制出相平面图和根轨迹图.实例分析结果表明,Duffing振子模型可用于二次交通事故演变过程分析,仿真结果为采取有效的二次交通事故预防措施提供了理论依据.

| Abstract: | In order to discover evolution of secondary traffic accidents and prevent from secondary traffic accidents,chaos characteristics of secondary traffic accidents are analyzed based on describing Duffing oscillator model.Afterwards,chaos model is established.By means of simulation,parameters values in chaos model are changed to obtain system constructions when periodic oscillation and chaos state occur.The phase plane and root locus diagrams are drawn.Case study shows that it is feasible to apply Duffing equat... |
