In this study, to reduce the torsional vibration force on a shafting, a two-points simultaneous measurement was performed for the damper inertia ring and damper casing parts of a high speed marine diesel engine crank shaft system with a viscous friction damper. The proposed method to directly measure the relative torsional angular displacement waveform of the damper inertial ring and casing parts is to simultaneously measure the dynamic torsional stiffness and damping coefficient. We used dynamic characteristics value obtained from measurements and performed numerical calculations (using the transfer matrix method) of the torsional vibration angular displacements and the torsional stresses of the viscous friction damper of the marine diesel engine crankshaft system.
Abstract
In this study, to reduce the torsional vibration force on a shafting, a two-points simultaneous measurement was performed for the damper inertia ring and damper casing parts of a high speed marine diesel engine crank shaft system with a viscous friction damper. The proposed method to directly measure the relative torsional angular displacement waveform of the damper inertial ring and casing parts is to simultaneously measure the dynamic torsional stiffness and damping coefficient. We used dynamic characteristics value obtained from measurements and performed numerical calculations (using the transfer matrix method) of the torsional vibration angular displacements and the torsional stresses of the viscous friction damper of the marine diesel engine crankshaft system.
