连续多点成形是一种先进的板料成形技术。通过调节柔性辊的曲率和上柔性辊的位移，可以加工出不同形状的三维曲面。设计了CMPF实验装置。建立了有限元分析模型。为了揭示连续多点成形的特点，将传统辊弯成形与连续多点成形进行了对比，并采用数值模拟方法对连续多点成形过程及柔性辊与板料之间的作用力进行了研究，为连续多点成形设备的优化设计提供了依据。对球面、马鞍面和扭曲面进行了模拟，并给出了实验结果。
Continuous Multi-Point Forming (CMPF) is an advanced sheet metal forming technology. It can manufacture three-dimensional surfaces of different shapes by adjusting the curvatures of flexible rollers and displacement of upper flexible roller. CMPF experimental equipment was designed. Finite Element Analysis (FEA) model was established. To show the characteristics of CMPF, conventional roll bending was compared with it. Process of CMPF and action force between flexible rollers and sheet metal were researched by numerical simulation method; simulation results can offer assistance to optimise the design of CMPF equipment. Spherical, saddle and twisty surfaces were simulated and their experimental results were presented.
