英文摘要：

The wheel pair of high-speed train plays a decisive role to the vehicle quality, it＇s significant to have a research and exploration on the modern design method for wheel pair. For the structure characteristics and design procedures of wheel pair, the theory of digitization design base on the modularization was proposed, the generalized modularization method will shown in this paper, and the design process for wheel, function module design were discussed in detail, the system functional module was divided into global parameter module, structural design module and analysis module. The structural design module based on the generalized-modularization approach included tread module, wheel pair module and axle module. By the method of object-oriented design, exploiting the CAD design platform for wheel pair and accomplish the digital design on wheel pair of high-speed train.
