Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 3
Abstract
[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.
