Abstract A mathematical model of a striplooper system of a hot strip tandem rolling mill is developed using Hamilton's principle and the Galerkin weighted residual method. Several nonlinearities are considered and the effects of bending and dynamic forces on the accuracy of the model are studied. Based on the model, an estimator for the strip tension is proposed. Finally, an impedance ...
