摘要：

基于板料为幂次强化材料模型的假定，根据外力做功与板料变形所消耗的内功相等的原理，建立了辊弯成形的理论分析模型，得出了成形力的数学计算公式，分析了各工艺参数对成形力的影响趋势。为了验证理论计算的有效性，建立了辊弯成形有限元仿真模型，对U型材的辊弯成形过程进行了有限元仿真计算。结果表明，成形力的理论计算结果和有限元仿真数据吻合良好；采用成形力计算公式的计算结果与现有文献中的实验测试数据符合程度较好。

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.
