| 摘 要： | 运行平稳性是机车车辆的重要指标。一般而言,机车车辆运行平稳性随着速度提高而下降。为了便于设计我国高速铁路机车车辆,本文提出一种估测机车车辆运行平稳性的方法,作为机车车辆在设计过程中优化结构和方案比较的手段。本文以东风9内燃机车为例,分析了各种速度下的平稳性指数,并比较了线性模型和非线性模型的分析结果。

| Abstract: | Riding quality is an important index of railway vehicle running behaviour. Generally riding quality becomes worse while vehicle running speed rises. In order to provide essential data for designing high speed railway vehicles, an analytical method for predicting riding quality of the vehicleis is developed. This method makes possible to optimize suspension parameters and to compare various designs of the vehicle. As an example,the riding index of diesel locomotive type DF 9 is calculated and the results of linear and nonlinear models of the locomotive are compared. |
