中文摘要:

      提出了一种适合高品质、大卷装收卷的控制张力设计方法。首先，介绍了收卷机张力控制的主要结构及其工作原理。再根据弹性力学原理，分析了收卷张力与卷装内应力分布的关系模型。在此基础上，讨论了恒张力收卷、锥度收卷和恒力矩收卷模型，并计算了其卷装的内应力分布情况。最后，提出了一种应用单纯形法进行最优收卷张力求取的方法。实验结果表明所提设计方法能有效保证所收卷的大卷装具有均匀的内张力分布。

英文摘要:

      A new design method to tension control in winding process is developed for producing high-quality large wound roll.Firstly,the work theory and equipment construction of tension control system in a winding machine are introduced.Secondly,the relationships between winding tension in the winding section and internal stress distribution within wound roll are analyzed based on the elasticity mechanics theory.Thirdly,the cases of constant tension,taper tension and constant torque winding are discussed,and the distributions of internal stress in the wound rolls are calculated.Finally,an application of simplex method to searching for the optimal winding tension is presented.The experimental results show that the proposed design method can ensure the internal tensions in a large wound roll to get uniform distribution.
