摘要

钢道岔是中低速磁浮线路系统的关键部件之一。然而,在主动控制下的车辆容易发生车道岔耦合振动,因此有必要通过现场试验来识别这种耦合系统的振动特性。为此,在某中低速磁悬浮试验线上对车辆-道岔耦合系统进行了动态性能试验。首先,获得了耦合系统在不同工况下的动态响应数据。然后,采用自由衰减法和有限元法对道岔的自振特性进行了分析,仿真结果与实测结果吻合较好;详细分析了耦合系统的加速度响应特性,并采用Sperling指数对整车平顺性进行了评价。最后,讨论了耦合系统的频率分布特性。试验结果可为中低速磁悬浮运输系统的模型验证和优化设计提供参考。

Experimental investigation on vibration characteristics of the medium–low-speed maglev vehicle–turnout coupled system

The steel turnout is one of the key components in the medium–low-speed maglev line system. However, the vehicle under active control is prone to vehicle–turnout coupled vibration, and thus, it is necessary to identify the vibration characteristics of this coupled system through field tests. To this end, dynamic performance tests were conducted on a vehicle–turnout coupled system in a medium–low-speed maglev test line. Firstly, the dynamic response data of the coupled system under various operating conditions were obtained. Then, the natural vibration characteristics of the turnout were analysed using the free attenuation method and the finite element method, indicating a good agreement between the simulation results and the measured results; the acceleration response characteristics of the coupled system were analysed in detail, and the ride quality of the vehicle was assessed by Sperling index. Finally, the frequency distribution characteristics of the coupled system were discussed. All these test results could provide references for model validation and optimized design of medium–low-speed maglev transport systems.
