基于虚拟样机的磁悬浮控制系统仿真

自从磁浮列车的概念诞生起，研究者们一直采用微分方程描述方法对系统进行研究。但是由于系统是多点耦合，并且严重非线性，这种传统的研究方法已经不能满足研究需要，磁浮列车的飞速发展迫切需要一种新的有效的研究手段。虚拟样机技术是近几年在国际上逐渐发展起来的，它利用三维实物图形建立模型，避免了描述微分方程的困难。文中利用AD—AMS虚拟样机软件组建详细的磁浮列车单个转向架三维模型，以垂向控制系统为研究对象进行虚拟样机仿真分析。最后给出了车辆慢慢悬浮和激励测试的仿真结果，这一结果与实验现象是一致的。该文将虚拟样机技术与磁浮列车系统技术研究有效地结合起来。

Controlling System Simulation of Maglev Suspension Bogie Based on Virtual Prototype

After the concept of maglev train came into being, the researchers have been analyzing the system by differential equation. The traditional method cannot satisfy the needs because the system is multi-points coupled and seriously nonlinear one. The rapid development of maglev train is eager for a new effective method. The virtual prototype technology has emerged for a few years. It builds 3D entities model to avoid the trouble of differential equation. Software ADAMS is applied to set up detailed 3D model of the maglev bogie and simulate the vertical suspension controller. The simulation results of slow suspension and square single test are given at last, which are consistent with the experiments. This paper effectively combines the virtual prototype technology with maglev train technology.
