Vibration and Control of Axially Moving Belt System : 4th Report, Effect of Inclined Angle by Experiment

Abstract

High-speed operation is required for industrial machines equipped with belt driving systems. The driving belt is, however, subject to a speed limitation due to the occurrence of bending mode resonance vibration caused by machinery error, e.g., pulley eccentricity. In order to reduce this resonance vibration, a parametric excitation method provided by belt tension fluctuation is proposed, based upon the concept of open loop vibration control theory. The belt driving systems require various setup angles. We tested the resonance vibration control for many inclined types of belt layouts along the horizontal to vertical ways. Parameter selection for optimum vibration control of inclined axially moving belts is verified through experimental data.
