| 摘 要： | 本文运用车辆-轨道耦合动力学新理论,仿真计算了列车以不同速度匹配通过不同类型纵断面时动力学性能的各项指标,并且根据现行铁道机车车辆动力学性能评定规范加以评价。结果表明:在本文设定的不同类型纵断面条件下,如单面坡划为多坡段或凹型坡加设分坡平段或凸型坡加设分坡平段,无论是高中速客车还是高低速客货混跑,采用新设计方案计算得到的指标略大于采用原设计方案得到的相应值,但差异不明显;所有方案下,除个别指标外,安全性指标均未超过合格限值,平稳性指标属优良等级。

| Abstract: | On the basis of the theory of vehicle -track coupling dynamics, the dynamics performance of passenger and freight trains passing through the different sections with different match speeds are simulated and evaluated systematically by using the railway vehicle and locomotive specification for evaluation of dynamics performance and accreditation test. Results show that the indices obtained from new design are largerer than those from old fan on the condition of different sections settled in the paper, and it is unobvious in the difference. Under all schemes, except one index, safety indices do not exceed limited values and ride performances are excellent. |
