摘要
本文采用整体模型与分割模型相结合的方法计算HC轧机的辊系变形。采用整体模型并利用功的互等定理和积分方法计算弯曲和剪切变形;采用分割模型的影响函数法导出辊系接触变形计算的统一表达式;考虑轧件弹性变形对出口板厚分布的影响;利用迭代法计算辊间接触压力分布和出口板厚分布。为进一步研究HC轧机提供了理论基础。
In this paper, the roll deformation is calculated with the combination of the common model and the point matching model. Based of the principle of mutually equal work and integration method, the bending and shearing deformation is computed in common model. All contact deformat,ion is calculated in one formula obtained from the point matching model. The distribution of contact pressure between rolls and the strip thickness after rolling are computed with iteration method. The influence of the strip elastic deformation is considered in all above calculation. It is the theory foundation of further study on HC mill.
