Title theory and numerical calculation of stiffness of mill 1780 - R2 under strip rolling

Abstract

The lateral stiffness and longitudinal stiffness of strip rolling mill is important for flatness and thickness control. The research of stiffness changing rule under different condition is of great significance for improving the precision of flatness and thickness control. Based on the CAE simulation software package-hypermesh, this paper put forward the method of meshing on model of strip rolling. On the background of strip mill roll shape design, detailed steps and methods of meshing is introduced. Compared with a lot of meshing models, this one motioned below is proved to be accurate and comprehensive.

This project adopt elementary theory of elasticity to calculate the stiffness of 1780-R2 mill during the process of rolling. Besides，it includes the calculation and analysis of the rack and deformation field of each power transmission components.
