摘要
本文将直达列车车流作为一个系统来考虑,该系统的输入为众多各异的车列所产生某去向列车的集结车辆,而输出为某去向列车车列。利用波谱分析方法,分析了该系统输入的非线性振动特性;发现其输入的波谱为一连续谱,从而揭示了该系统输入的非线性振动的内在机理——这种不规则的振动具有混沌特性,其吸引子为—混沌吸引子。
The paper treats the through train flow as a system, the inout of which consists of the nymbers of assmbling wagon of the train to a station and the outout is a through train to a station. By the method of spectrum analysis,the characteristics of nonlinear oscillations of the system input are analysed. The continuous formation of the specturm distibution shows that the mechanism of the nonlinear oscillations of the system input is that the irregular oscillations possess the characteristics of chaos and the attractor is a strange attractor.
