【摘要】 用有限元法计算并分析了三辊楔横轧机机架的强度,得出了机架各部位的应力状态及应力值,绘制了典型断面及机架外廓的主应力图。针对机架应力集中严重部位,对其结构与参数做了研究,找出了合理的结构参数值,为机架的改进和设计提供了理论依据。更多还原

【Abstract】 Introducing finite element method(FEM) to analyze the stress of a 3-high cross-wedge mill stand. We obtain the stress state and values of all the positions of the mill stand,with a major stress distribution diagram on stand contour and typical cross section plotted. The structural parameters of mill stand are discussed specially on the positions where the stresses are concentrated onto seriously,and reasonable ones are thus found out. All these provide a theoretical basis for the improvement of design of the mill stand.更多还原
