新结构高速磁浮列车动力学分析

Dynamics of new structure high-speed maglev vehicle

为了降低磁浮列车与轨道梁的垂向耦合振动强度,提高磁浮列车的曲线通过能力,对TR08磁浮列车的走行部结构进行了改进设计。通过移植TR08磁浮列车模型的功能模块,构建了新型磁浮列车动力学模型,并模拟分析了车辆、轨道梁的动力响应和曲线通过性能。结果表明:新型磁浮列车降低了轨道梁的响应,提高了曲线通过能力,其设计思路合理。

In order to reduce the vertical vibration intensity of the maglev train and the track beam,improving the curve passing capacity of the maglev train,the structure of the running part of the TR08 maglev vehicle was improved.By transplanting the functional modules of the TR08 maglev vehicle model,a new type of maglev vehicle dynamics model was created.The dynamic response and curve passing performance of the vehicle and the track beam were simulated and analyzed.The results show that the new maglev vehicle reduces the response of the track beam and improves the curve passing ability,and that the design idea is reasonable.
