中文摘要:
      基于直线电机车辆的基本结构及工作原理,利用拉格朗日-麦克斯韦方程,从机械与电磁能量层面进行了直线电机车辆系统机电动力学模型的构建。分析了车辆系统机械部件及电磁部分的相互作用规律,并推导了相关微分方程。根据Clark变换,将所得的三相坐标系模型简化为两相坐标系模型。应用Matlab求解及仿真,得到相关参数的变化规律。以此方法建立直线电机车辆的机电动力学模型,简单有效地解决了相关的机电动力学问题。
英文摘要:
      Based on the basic structure and working principle of linear motor vehicle, the electromechanical dynamics model of linear motor vehicle system is constructed from the mechanical and electromagnetic energy level by using the Lagrange-Maxwell equation. The interaction rule of mechanical components and electromagnetic parts of vehicle system is analyzed, and the related differential equations are derived. According to the Clark transform, the obtained three phase coordinate system model is simplified to two phase coordinate system model. The change rules of the relevant parameters are obtained by Matlab solving and simulating. The electromechanical dynamics model of the linear motor vehicle is established by this method, and the related electromechanical dynamics problems are solved simply and effectively.
