Vibration coupling analysis of band/wheel mechanical systems

Measurements of vibration on continuous bands driven by rotating wheels show coupling occurs between vibration of the band spans and wheels. Significant error in the predicted vibration spectrum and the response of a span can occur if the coupling is neglected. An analytical model describing the vib...

Description
Summary:Measurements of vibration on continuous bands driven by rotating wheels show coupling occurs between vibration of the band spans and wheels. Significant error in the predicted vibration spectrum and the response of a span can occur if the coupling is neglected. An analytical model describing the vibration of the band/wheel system is presented. When the equilibrium curvatures of the band spans are finite, the transverse motion of the spans are linearly coupled to their longitudinal motions and to the oscillation of the wheels. The analytical predictions are validated by comparisons with experimental observations. The importance of the band tension, the band transport speed, the wheel inertias and radii, and the wheel support stiffnesses to the coupling are discussed. The model can be utilized in analysis of active and passive vibration control of band/wheel systems.
