Shunting Modularization Designs

It is required that the technical performances and levels for railway transportation equipment should be more advanced due to the fast developed national economy. Along with on-board devices getting more and upgraded, their components are required to be integrated and modularized; and, because of transportation capability and efficiency advancement, the locos of different power levels are requested to be serialized and standardized. Thus, modularized designs for shuntings are also in a great need so as to simplify or serialize the loco assembly as facing with higher loco customizations and stronger markets competitions. Thereby, it is going to construct epoch loco technology and product flats.Shunting modularization designs have adopted various of advanced international and domestic loco manufacturing technologies applying for better performances, which can not only improve loco manufacturing technologies and application reliabilities, but also decrease much maintenance work as well as save many human and material resources, and this can push railway transportation into a long-term expansion.This paper describes Dong Feng 10DDA Locomotive as one being applied with modularization design development methods. It also describes the relations between product flat and technology flat, the construct modes and characteristics of product flat and layout of this loco design. It calculates and validates this loco's traction and cooling performance parameters in details, and introduces the structure and controlling principles of its microcontroller, concludes 3 technology aspects and basic technological analogy aliases of this loco's modularization design. It adopts both international and domestic advanced loco manufacturing technologies and has mature, economic and applicable components. It is paid much more'standardization, modularization and serialization'during its design process, which founds a firm base for future shunting modularization design.
