Abstract: A 2-D finite element model for dynamic analysis of four-high rolling mill is presented, which is composed of beam elements, rod elements, spring elements and mass elements. Based on the theory, the excitable nature frequencies of rolling mill can the calculated. Experiment shows that the natural frequencies got from theoretical formulae are good approximations compared the values measured.
