城轨塞拉门虚拟样机建立方法研究

Research on the Establishment Method of the Virtual Prototype of the City Track Sliding Plug Door

基于Recur Dyn和Matlab/Simulink的机电联合仿真分析功能,模拟了城轨塞拉门的开关门过程,提出了一种城轨塞拉门虚拟样机建立方法。首先建立机械系统仿真模型,然后采用速度、电流双闭环控制建立控制系统仿真模型,再将机械系统与控制系统相结合建立机电联合仿真模型。对仿真模型进行仿真分析,将仿真结果和实验结果进行对比,根据对比结果对机械系统和控制系统的仿真模型进行修正。最后对塞拉门的部分亚健康工况进行了仿真模拟,进一步验证了机电联合虚拟样机的正确性。

Based on the electromechanical co-simulation function of RecurDyn and Simulink, the opening and closing process of the sliding plug door was simulated, and an establishment method of the virtual prototype was proposed. Firstly, the simulation model of the mechanical system was established, then the speed and current double closed-loop control was used to simulate the control system. The mechanical system was combined with the control system to establish the electromechanical co-simulation model, then the co-simulation model was simulated and analyzed, and the simulation results were compared with the experimental results. According to the comparison re-sults, the simulation models of the mechanical system and control system were modified. Finally, the simulation of the partial sub-health conditions of the sliding plug door were carried out, which further verified the correctness of the electro-mechanical integration virtual prototype.
