摘要

虚拟轨道列车（VTT）是一种新颖的城市交通解决方案，它结合了公路和铁路车辆的元素。目前，虚拟轨道列车已在宜宾、株洲、哈尔滨和盐城等多个城市得到广泛应用。尽管其应用日益广泛，但 VTT 独特的结构和复杂的轮胎-地面相互作用给轮胎磨损带来了巨大挑战，这已成为一个亟待解决的问题。本研究建立并验证了 VTT 的多体动力学模型及其轮胎的有限元模型。从不同角度研究了轮胎与地面的接触行为和边界条件，以计算轮胎磨损。模拟结果表明，轮胎内部压力、VTT 的负载、路面状况、倾斜角度和轮胎打滑都对 VTT 的轮胎磨损有关键影响。这些研究结果表明，必须谨慎管理 VTT 的运行条件，以减少轮胎磨损，确保安全运行。此外，对 VTT 轮胎磨损机理的研究结果为 VTT 的优化和维护提供了宝贵的启示。

Study of the tire wear of virtual track train

The Virtual Track Train (VTT) represents a novel urban transportation solution that combines elements of both road and rail vehicles. Currently, VTT has gained significant adoption in several cities in China including Yibin, Zhuzhou, Harbin, and Yancheng. Despite its growing usage, the unique structure and complex tire-ground interaction of VTT pose significant challenges in terms of tire wear, which has become a pressing issue. This study develops and validates a multi-body dynamics model of VTT along with a finite element model of its tire. The tire-ground contact behavior and boundary conditions are studied from various perspectives to calculate tire wear. The simulation results demonstrate that the internal pressure of the tires, the load of VTT, the pavement conditions, the inclination angle, and slippage of tires all have critical effects on VTT’s tire wear. These findings suggest that the operating conditions of VTT must be carefully managed to reduce tire wear and ensure safe operation. Furthermore, the research results of tire wear mechanism of VTT offers valuable insights for the optimization and maintenance of VTT.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
