摘　　要：为了准确描述1400mm十二辊轧机轧辊间的接触压力分布规律,以有效改善其轧件的横向厚度差和板形,本文应用应力相似准则设计了1400mm十二辊轧机光弹模型,并用三维光弹性应力分析原理,实验确定1400mm十二辊轧机光弹模型的辊间接触压力的分布规律,并依据应力相似转换准则,计算出其实际轧机辊间接触压力分布,对1400mm十二辊轧机压力分布的进一步理论计算、辊型设计的优化以及轧件横向厚度差和板形质量的控制有着重要的实验指导意义。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.
