摘　　要：考虑轮轨接触几何关系、轮轨相互作用力和悬挂装置等非线性因素,利用动力学仿真软件,建立了公铁联运多功能运输车动力学模型,仿真分析了车辆系统的运动稳定性、曲线通过安全性和运行平稳性。研究结果表明:在新车和磨耗状态下,公铁联运多功能运输车空车、重车载荷工况的临界速度具有一定的速度裕量,曲线通过安全性指标均满足GB/T 5599-1985的限度要求,垂向和横向平稳性指标均<4.0良级标准,动力学性能良好,能够保证以120km/h速度正常运行。In consideration of the nonlinearities resulting from wheel-rail contact geometry,wheel-rail interaction force and suspension characteristics,the dynamic model of rail-road intermodal transport multi-function vehicle is established by using dynamic simulation software,and the running stability,curve negotiating performance and riding quality of the vehicle system are simulated and analyzed.The results show that under the new car and wear condition,the vehicle runs at enough high hunting critical speed,its safety indices of the curve negotiation meet the limit requirement of GB/T 5599-1985,the vertical and lateral ride quality indices are less than 4.0.And the good dynamic performance can guarantee the normal operation speed of 120 km/h.
