摘要
为了解决收卷带材中经常出现的靠内芯处的皱折和带材厚薄不均匀的情形 ,首先从弹性理论出发 ,给出了卷筒内张力和应变分布公式 ;根据这组公式讨论了恒张力卷绕和锥度张力卷绕下卷筒内的张力分布 ,从而导出了不起皱折的必要条件。然后给出了在两种理想的卷筒内张力和应变分布的情形 ,即卷筒内等张力和等应变分布条件下 ,卷绕张力的计算公式。
From the theory of elasticity,the formulas for the distributions of tension and strain in a wound reel are suggested to solve that there often exit the fold and nonuniform thickness in wound reels.Based upon these formulas the cases of constant and taper winding tension are discussed,and the distributions of tension in the wound reels are calculated.Therefore,the necessary conditions without any fold are given.Two ideal cases are suggested,which are the distributions under the condition of uniform tension and strain in the wound reels.The corresponding winding tension can be calculated by the suggested formulas.Finally,the control system is supposed to realize these uniform tension and strain.
