Absrtact:The track-based traditional mode for transferring and parking car body of the metro vehicle restricts the ability to repair vehicles in the shed for intermediate repair and heavy repair.Using the technology of automatic guided vehicles,a trackless automatic transportation system is studied and proposed,and the layout of maintenance workstations in the shed for intermediate repair and heavy repair is optimized in order to automatically transfer and park the car body of the metro vehicle during the process of the intermediate repair and heavy repair.The test results show that adopting a trackless automatic transportation system and supporting process planning,not only can the car body of the metro vehicle be safely and effectively transported automatically,but also the land utilization rate of the maintenance depot can be improved,and the capacity of maintenance vehicles can be enhanced.
