Abstract
With the rapid expansion of rail transit networks,the demand for maintenance,inspection,and emergency rescue of rail infrastructure continues to grow.Existing dedicated rail vehicles are increasingly limited in terms of mobility,response speed,and adaptability when dealing with complex operating scenarios.Road-rail mobile platforms,which can travel on both roads and railway tracks,have therefore become an important type of equipment for enhancing the efficiency of rail system support.This paper focuses on the configuration classification and key system arrangements of road-rail mobile platforms,and presents a systematic review and engineering-oriented comparison of the relevant technologies.The differences between guiding-wheel and powered-axle configurations,together with their applicable scenarios,are analyzed in detail.Their key technologies including bogies,guiding assemblies,driving modes,rail-wheel configurations,and on-track deployment mechanisms are compared and summarized.On this basis,future development trends of road-rail mobile platforms are discussed,aiming to provide a reference for the development and wider application of related technologies.关键词
