A broad range of complex vibration problems can occur on paper machines.  These include nipped roll interactions, problems with roll drive systems, and structural issues (including resonance).  Successful analysis and resolution of paper machine vibration problems requires a thorough understanding of the equipment, and the ability to apply various diagnostic techniques. This paper will present several case studies, each describing the evaluation techniques used to diagnose a paper machine vibration problem.
