The rotor dynamics of reeling machinery

摘要

Wide-faced rotors for high-speed reeling operations such as those employed in paper manufacture, printing, coating and laminating are considered, and he torsion behavior of these units is investigated. Modeling, simulation and analysis techniques are involved enabling the prediction of he torsion vibrational signature of high-speed assemblies under acceleration and braking conditions. The results outlined show that simulated response characteristics can be easily obtained, and the effect of varying the rotor geometry can be routinely accommodated. The transient conditions presented for a reeling machine are commented upon with particular reference to the angular velocity and shear stress variation following torque changes. The effect on volume production is discussed.
