| 摘 要： | 本文根据车辆－轨道耦合动力学原理，建立车辆－轨道垂横耦合模型，并进行全面的验证：首先与国际著名软件NUCARS进行对比；其次与车辆－轨道垂向耦合模型得到的车辆和轨道系统垂向随机响应对比；然后与鹰厦线小半径曲线试验结果对比；最后与货物列车的线路试验结果对比。对比结果有力地验证了车辆－轨道耦合系统垂横模型及其求解方法的正确性和合理性，为车辆－轨道耦合系统垂横模型的广泛应用奠定了基础。

| Abstract: | In the paper,the vertical_lateral model of vehicle_track coupling system is set up according to the theory of vehicle_track coupling dynamics and four aspects of numerical simulation verification are carried out.Firstly the results of the new model are compared with that of the famous NUCARS software;secondly,compered with that of the vertical model of vehicle_track coupling system;thirdly,compared with that of tests on small radius curve track at YING_XIA line of our country and fourthly,compared with that of our country freight train tests.Comparison results indicate that the vertical_lateral model of vehicle_track coupling system is correct and reasonable and it lays a foundation for wide application to the vertical_lateral vehicle_track coupling problems. |
