Numerical Simulation and Process Test for Cold Extrusion of Wheel Hub Bearing Rings
Abstract:
This paper describes procedures and results obtained using 3D rigid plastic thermal-mechanical finite element model of wheel hub bearing rings. Numerical simulation for cold extrusion process is performed and metal flow characteristics, distribution of effective stress & temperature field and load-stroke curve are analyzed. Approach of tool wear prediction is also explored using Archard model . Process test revealed that numerical simulation provides theory basis and useful guidance for cold extrusion process specification and die design.
