Abstract

Computation of Vibrations in the Steel Strip Coiling Process of a Steckel MillAbstract: The reduction of vibrations in a Steckel-Mill during the production process is important in order to produce high quality flat products. With the derived mechanical model, it is possible to study the influence of geometric and process parameters. It is necessary to get a reduced mechanical model for the non-linear dynamic and elasti- cally coupled multi-body system. A suitable time-integration method computes the solution for the dynamic system for a rapid long-term coiling process with a time-step, which guarantees a converged solution. The analysis of the computation results shows the influence of the parameters and operation conditions to the vibration amplitudes and serves in finding improved parameters for the production process. Furthermore a reduced mechanical model with adjusted parameters allows the combination with a controller.
