Component type selection system and method suitable for locomotive and bullet train converter

The invention relates to model selection of a locomotive and bullet train converter, belongs to a product early-stage design stage, and particularly relates to a part model selection system and method suitable for the locomotive and bullet train converter. The invention aims to provide a part type selection system and method suitable for a locomotive and bullet train converter by establishing a supplier product type selection library, digitally packaging parameters in a technical standard/technical specification and establishing an interface with a product data platform. According to the system and the method, data of the platforms are called through interfaces to be used in part type selection method calculation, and designers are helped to quickly complete type selection calculation and output design calculation reports. Meanwhile, part design data can be transmitted back to a product data platform to be used as reference for other product design. The model selection method is embedded in the product design
