Abstract
As a result of more requirements for improving natural environment and economic environment, the manufacturing of light weight components is becoming increasingly vital in industrial development. Variable thickness rolling (VTR)-a new process for rolled profile strips (RPS) is proposed in this paper. This so-called “variable thickness rolling” is based on the utilization of a special roll system that causes the material to flow in latitudinal direction. The rolled profile strips with defined cross-sections are obtained by this process. The elastic-plastic finite element model is established to analyze the forming principle. The simulation results agree with experimental data on the whole.
