Analysis of chattering phenomenon in industrial S6-high rolling mill. Part II: Experimental study

The paper represents an extension of a previous work where the problem of chatter in a rolling mill producing advanced high-strength steels (AHSS) was investigated by a combination of a linear lumped parameter model and the slab analysis. In this paper the authors show the detailed experimental study of the problem with a complete description of all the phases related to the vibrational investigation that lead to the solution of the problem. Furthermore, a different model based on the Orowan's method together with a nonlinear model of the rolling mill is presented and simulations are performed.
