  • vibration analysis of paper machine s asymmetric tube roll supported by Spherical Roller Bearings
    Mechanical Systems and Signal Processing, 2018
    Co-Authors: Janne Heikkine, Ehnam Ghalamchi, Raine Viitala, Jussi Sopane, Jari Juhanko, Aki Mikkola, Petri Kuosmane
    Abstract:

    Abstract This paper presents a simulation method that is used to study subcritical vibrations of a tube roll in a paper machine. This study employs asymmetric 3D beam elements based on the Timoshenko beam theory. An asymmetric beam model accounts for varying stiffness and mass distributions. Additionally, a detailed rolling element bearing model defines the excitations arising from the set of Spherical Roller Bearings at both ends of the rotor. The results obtained from the simulation model are compared against the results from the measurements. The results indicate that the waviness of the bearing rolling surfaces contributes significantly to the subcritical vibrations while the asymmetric properties of the tube roll have only a fractional effect on the studied vibrations.
