摘　　要：采用理论解析方法,建立了宽板V型自由弯曲的数学解析定量描述模型。首次采用梁的弯曲理论和能量法结合的方法推导了弯曲力和行程的理论解析公式。理论结果与实验数据进行了比较,证明理论解析定量描述模型与实际智能化折弯相符。对进一步研究板材弯曲成形智能化控制的识别和预测提供了可靠依据。This thesis establishes the quantitative descriptive model of mathematical analysis in V-shape free bending of wide sheet metal by using theoretical analysis method. It firstly derivates theoretical analysis formula of force and stroke by using beam bending theory and energy method. The experiment approves that the theoretical analysis quantitative descriptive model consonants with actual V-free bending＇ by comparing. It provides the theory base for further study of identification and prediction in intelligent control of sheet bending forming.
