| 摘 要： | 以100 m长钢轨采用换长1.5和1.3普通平车装载加固方案为例,建立长钢轨运输动力学仿真模型.对车组以不同速度侧向通过9号和12号道岔,以及通过半径为300 m曲线的工况进行动力学仿真计算.结果表明,车组的各项动力学指标均满足运输安全要求;各工况下动力学指标随着车辆运行速度的提高而增大,但脱轨系数最大值与速度关系不大...

| Abstract: | The dynamic models for the transportation of long steel rails were established according to the loading and reinforcing schemes for 100 m long steel rail transported by flatcars whose underframes were 15.4 and 13 m in length.The dynamic simulation was carried out under various loading conditions,such as laterally passing No.9 and No.12 turnouts at different speed and passing the curve of 300 m radius.The results indicate that the dynamics indexes of the flatcar trainset meet the requirements for transportat... |
