提出一种四辊轧机动态性能分析的平面有限元模型 ,该模型由梁单元、杆单元、刚度单元和质量单元等组成。根据该理论 ,可计算得到轧机容易激发的固有频率。用试验检验了所提模型的正确性
This paper presents a plane finite element model of the dynamic performance analysis of a four-high rolling mill. The model consists of a beam element, a rod element, a stiffness element and a mass element. According to this theory, the mill natural frequency that can be excited easily can be calculated. The correctness of the proposed model is tested by experiments
