【摘要】 近十年来，ＧＹ型短应力线轧机在我国获得了广泛的应用。本文对ＧＹ型短应力线轧机主要受力零件轴承座进行了光弹实验和三维有限元计算，得出了轴承座应力分布规律，校核了强度，并为今后进一步改进结构形式提供了可靠依据。更多还原

【Abstract】 In the last ten years,the GY type short-stress path mill had been widely used in China.In this paper,the photoelastic experiment on bearing stock,which is the main heavy loaded part of GY type short-stress path mill,is introduced and the experiment results are analysed by means of three-dimensional finite element method,then the law of stock stress distribution is obtained and the mill strength is evaluated.A reliable basis for the further improvement of mill construction in the future is provided.更多还原
