Rolling is one of the important fornring processes of railway wheels. The purposes of the rolling are to extend web length and increase the inner and outer diameters of the forged wheel preforms, as well as to precisely form the rim, flange and tread of wheel in rolling process. Wheel rolling is a kind of non-symmetrical and multi-passes ring rolling process. Furthermore, wheel rolling has more deformation tools and the movements of tools are more complex than ordinary ring rolling. The wheel deformation in rolling is analyzed based on finite element method in this research. The process of wheel vertical-type rolling, together with modeling this process by using commercial package MSC. SuperForm, is described in detail in this study. Three dimensional thermo-mechanical coupled analyses are conducted for rolling the railway wheel. The results show that: (1) during the rolling forming, the largest strains are distributed in the conjunction region of web and rim; the strains in the outer part of rim is significantly larger than those in the inner part; strains in the central part of the rim are small. So it can be predicted that the dynamic recrystallizaiton in rim center is unlikely take place; (2) The metal in the web flows significantly in circumferential direction in the wheel rolling, especially in mid- and late rolling period; (3) The rolling forces of rollers are obtained and compared with the measured forces. The calculated forces are in good agreement with the measured forces. The successful three dimensional modeling of railway wheel rolling forming provides bases for optimization of wheel rolling process.
