3D Photoelasticity Analysis on Contact Force in 1400mm 12-h Mill

摘要

In order to accurately describe the contact force distribution between rolls of 1400mm 12-h mil, and improve the plate shape and transverse thickness difference of work piece, a photoelasticity model of 1400mm 12-h mill was designed in this paper based on the principle of similarity. 3D photoelasticity analysis was applied to determine the contact stress and force distribution between the rolls of 1400mm 12-h mill, and the actual contact force distribution between rolls was calculated in accordance with the similarity principle. It was an important experimental guidance for further theoretical calculation of rolling force distribution of 1400mm 12-h mill, roller shape optimization, plate shape and transverse thickness control.
