Rotary forging technology is the last century, the pressure of the emergence of a new processing method, because it has save effort, saving materials and many other advantages, many countries have spent a lot of manpower and material resources involved in rotary forging Technology. Train wheel rotary forging forming process is a new wheel technology, It has many advantages over traditional methods such as high materials utilization, high mechanical property and high forming dimensional accuracy etc, It has a wide application and development space in the future.According to the prototype railway wheels, Using three-dimensional shape software UG processing of the wheel and rotary forging process upper and lower mold solid modeling, Get the wheels of rotary rolling forming blank and die model forming for rotary rolling forming simulation analysis provides preconditions.Based on the rigid plastic finite element theory, established the wheels rotary rolling forming finite element analysis of numerical model. Using finite element analysis simulation software Deform-3D, application of three-dimensional rigid plastic finite element method for the wheel rotary rolling forming process simulation analysis, the railway wheels rotary roll metal blank forming process of metal flow patterns and characteristics of filling, focus on the different blank shape on the forming quality of the wheel, through the forming process of different rough analysis, get the optimal rotary roll blank for machining the wheel, and numerical simulation analysis of the optimal blank, the optimization of the equivalent stress distribution of rough and dies the forces, and compared the force with the forging die, for rotary rolling forming provide a theoretical basis.With the great development of railway, rolling on the laboratory test rig demand is also growing, track and wheel type in the number of corresponding increase in demand on the traditional processing methods can not meet the demand. This establishment of Deform-3D numerical simulation model, combined with rules of forming the wheel track wheels Orbital simulation processing of the metal flow pattern. Exploratory study of the use of rotary forging technology to process rolling test bed rail wheels feasibility.
