Railway container car design method and system

The invention discloses a railway container car design method. The method comprises the following steps of: obtaining a configuration module of a product from a first module library, wherein the configuration module comprises bogie, a braking device, a coupler buffer device and a container locking device; obtaining a structure module of the product from a second module library, wherein the structure module comprises a middle beam, a sleeper beam, a side beam and a cross beam; and assembling the obtained configuration module and structure module into a first product model. According to the method, the configuration module of the product is obtained from the first module library, the structure module of the product is obtained from the second module library, and the obtained configuration module and structure module are assembled into the first product model, so that the size change of the first product model can be subsequently driven according to product performance parameters, and theconfiguration module and
