摘要
本文根据弹性理论,推导出具有可控刚度卷筒卷取机上冷轧钢卷内部应力的计算公式,建立了考虑带卷层问变形效应的应力分布的数学模型,并编制了源程序。文中还分析了各机械参数(卷筒半径及刚度、钢卷外径、带钢张应力、带钢厚度等)对钢卷内部应力分布的影响,其可靠性已为森吉米尔可控刚度卷取机上进行的实验研究的结果所证实。
According to the theory of elasticity, the author has established analytic formulas for the stresses inside cold—rolling strip coil on the controlled collapse winder,and developed a mathematical model and computer programs for the stress distribution in strip coil as regards'the deformational effects between the layers of the strip coil'. Computer results have shown how the mechanical parameters (radius of mandrel, stiffness of mandrel, external coil radius, winding tension of strip,strip thickness etc)influence the stress distribution inside the strip coil. The reliablity of above engineering calculation methods have been confirmed by testings on Sendzimir controlled collapse winder.
