Abstract：

Based on assumptions of power strain-hardening model for sheet, and the equal principle of external work and internal energy dissipated by deformation, a theoretical expression of forming force was obtained. Then, the influences of technological parameters on the forming force were analyzed. In order to verify the validity of theoretical results, a FEA model of rolling U-shaped profile was established, and the rolling process was simulated. The result shows a good agreement of forming force between theory and numerical simulation. Calculation results by using formula for forming force are in well accordance with the experimental data in the existing literature.
