Abstract: Rail vehicle bogie is a thorny problem to achieve rapid custom design of the bogie driven by diverse and individualized demands in the development process of rail vehicle.Aiming at the lack of systematic methods and tools in rapid custom design of bogies，a set of design methods for vehicle bogie based on modular configuration is presented and the corresponding design prototype system is developed. Based on the product family information model of bogie on the basis ofGBOM （Generic BOM），the extended bogie configuration model is constructed by combining the multi-level 3D skeleton model and the module configuration design process model.Based on the extended configuration model，a systematic bogie modular configuration design process that adopts casebased reasoning technology and parametric design technology is proposed to realize the rapid custom design of bogie driven by individualized demands. In addition，a prototype system for the modular configuration design of rail vehicle bogie has been developed and tested by the application in enterprises，which verified the feasibility and effectiveness of the proposed method.
