Abstract

The stability of a tandem mill is analysed by considering interstand interactions. In this part of the paper the stability of the multistand multimodal chatter model, developed in Part 1 [1], is ascertained. The general model is represented in a simplified form, which highlights only phenomena caused by strip velocity, or equivalently, strip tension variations between stands. This mechanism constitutes one of the most critical sources of selfexcitation in the operation of tandem mills and leads to the most detrimental effects associated with third-octave mode chatter. As before, the theoretical analysis of the stability conditions is followed by a simulation study that shows the major dynamic trends in the mill's behaviour.
