Abstract

The rubber surface of a smoother roll in a paper making machine is deformed into a certain convex polygon at a high nip force and a high operating speed of the rolls rotating in contact with each other viscoelastically. The polygonal deformation occurs gradually, which leads to strong vibration of the machine. This paper describes the model of this system, which treats this vibration phenomenon as instability due to a time lag, and a theoretical analysis of this phenomenon. We also conducted an experiment to identify the parameters for use in the analytical model. From the test results, we found that deformation recovery characteristics of the rubber are time- dependent. The numerical results showed good agreement with actual results from machines.
