A simple 2D-model for vibration analysis of hydromechanical roll systems

In this paper a two-dimensional hydro-mechanical simulation model for a deflection compensated roll system is presented. This model includes several details, which call for special modelling techniques. The simulation model consists of several submodels such as the hydraulic system, the rotat-ing flexible shell, the hybrid pad bearings, the rolling contact, the sliding contact, and the paper web with a defect. Between these subsystems appear various interactions, e.g., in the form of forces. The obtained results indicate that the model can describe the basic dynamic behaviour of the system
