摘　　要：采用有限元法对支承辊辊系各个单元进行建模,计算了支承辊辊系单元的临界转速与不平衡响应。以某支承辊辊系为研究对象,分别对其固有频率、振型的模态分析、不平衡响应及周期性外载荷作用下的谐响应进行了分析计算。结果验证了本方法在进行支承辊辊系动力特性分析的有效性和精确性,从而为提高支承辊辊系的设计计算精度提供了一种新思路。In this paper, the finite element method is used to model each element of the backup roll system, and the critical speed and unbalanced response of the backup roll system element are calculated. Taking a backup roll system as the research object, the modal analysis of its natural frequency and vibration mode, unbalanced response and harmonic response under periodic external load are analyzed and calculated. The results verify the effectiveness and accuracy of this method in analyzing the dynamic characteristics of backup roll system, which provides a new idea for improving the design and calculation accuracy of backup roll system.
