摘　　要：锥辊不均匀压下板带面内弯曲成形结果取决于加载辊缝 ,而成形装置的加载辊缝与原始辊缝不等。在模拟装置上实现了成形过程 ,给出了加载辊缝的变化参数。基于梁的弯曲变形理论 ,建立了用于预测辊缝变化参数数学模型 ,编制了相应的计算软件 。In plane bending of strip under unequal compression with conical rollers is an advanced forming process, where unequal deformation is made use of.The formed ring is determined by the loading wedge gap that differs from the original wedge gap of the in plane bending analog apparatus. With the apparatus, the forming is completed and the gap change parameters describing the difference between the loading gap and the original gap are given.Based on the beam bending deformation theory, a model predicting the gap change parameters is established and the corresponding computation code is developed. The availability of the model is proved by experiment.
