摘要:
［目的］为了提高轨道交通车辆仿真系统的可视化与交互性，依托VR(虚拟现实)技术，构建了轨道交通车辆数字孪生仿真平台。［方法］通过轨道交通车辆数字孪生三维模型与机理模型的层级式构建方法，以及层级式关联映射方法，实现了三维模型与机理模型融合，耦合生成了轨道交通车辆数字孪生三维物理模型，并由此提出了一种轨道交通车辆数字孪生仿真系统以及系统的构建方法。以青岛某地铁车辆及其相应运行线路为研究对象，通过搭建的VR平台及车辆自动驾驶控制算法，对该仿真系统功能进行了试验验证。［结果及结论］试验表明，列车实际运行速度与控制运行速度误差均在±1.5 km/h内，证实了模型的有效性。轨道交通车辆数字孪生仿真平台的构建方法为提升轨道交通车辆仿真系统的可视化与交互性提供了新的技术思路。
Abstracts:
［Objective］ In order to improve the visualization and interactivity of the vehicle simulation system in rail transit, a digital twin simulation platform of rail transit vehicle is built based on VR (virtual reality) technology. ［Method］ Through the hierarchical construction method for digital twin 3D model and mechanism model of rail transit vehicles, and the hierarchical association mapping method, the fusion of 3D model and mechanism model is realized, and the digital twin 3D physical model is coupled and generated. On this basis, a digital twin simulation system and the system construction method for rail transit are proposed. With a metro vehicle and its operating line in Qingdao as the research object, the effectiveness of the digital twin simulation system is verified through the VR platform and the train automatic driving control algorithm. ［Result & Conclusion］ The test results show that the error between the actual running speed and the control running speed is within ±1.5 km/h, proving the validity of the model. The construction method of digital twin simulation platform for rail transit vehicles provides a new technical idea for improving the visualization and interactivity of the vehicle simulation system in rail transit.
