| 摘 要： | 为了研究城轨磁浮车辆的动力学特性,利用Catia及ADAMS软件,通过合理简化,建立了五转向架城轨磁浮车辆的动力学虚拟样机模型,并对该模型进行了两种工况下的数值仿真.在静悬浮工况下,车体在垂向、横向和纵向都产生振动,但以垂向振动为主,通过分析垂向振动参数,证明车辆具有较好的平顺性指标.在R70m的弯道工况下,仿真值与计算值基本一致,验证了模型的正确性.

| Abstract: | In order to reveal the dynamic characteristics of urban-rail magnetic levitation vehicle with five bogies, a virtual prototype model of the vehicle is established with software Catia and ADAMS after a reasonable simplification. Then, a dynamic simulation of the model is carried out in two different operating conditions. The results indicate that, when the vehicle is statically levitated, the carriage body vibrates in lateral, longitudinal and especially vertical directions. Moreover, by analyzing the vertical vibration parameters, it is found that the vehicle is of good ride comfort. The proposed model is proved correct by the consistency of simulated results with the calculated ones when the vehicle goes through a R70m curve. |
