为了完善中低速磁浮列车的悬浮控制系统,进一步提高列车运行的稳定性和可靠性,文章取单悬浮架模块系统进行分析,通过对簧上部件、空气弹簧、簧下部件、弹性轨道进行数学建模,获得整个系统的数学模型。此外,文章还通过三维有限元分析和线性插值获得任意电流和悬浮间隙下的悬浮力,进一步提高了悬浮力模型的精度。最后采用MATLAB对整个系统进行仿真分析。与传统的单点悬浮控制模型相比,文章所建模型更符合中低速磁浮列车的实际工作情况,为后续悬浮控制系统的设计和控制参数的计算奠定了一定的基础。
In order to perfect the suspension control system of medium and low speed maglev train and further improve the stability and reliability of the train operation, this paper analyzes the module system of single suspension suspension system. By mathematically constructing the sprung member, air spring, unsprung member and elastic track, Model, get the mathematical model of the whole system. In addition, the paper also obtains the levitation force under any current and suspension gap through 3D finite element analysis and linear interpolation, further improving the accuracy of the levitation force model. Finally, the whole system is simulated by MATLAB. Compared with the traditional single-point suspension control model, the model built in this paper is more in line with the actual working conditions of the low-speed maglev train, which lays a foundation for the design of the suspension control system and the calculation of the control parameters.
