Torsional vibration modeling and dynamic simulation of a rolling stand power transmission system

摘要

Vibration can be a serious problem with rolling mill equipment. To avoid vibration problems, it is important to predict system characteristics and dynamic performance at the design stage. This prediction can be achieved through vibration modelingand rolling process simulation. A new method of simulating torsional vibration for the power transmission system of a typical mill stand is described. System natural frequencies and vibration mode shapes are evaluated. Vibration responses and dynamic load factors are predicted. Predicted performance and field test results are consistent.
