Investigation of an Electromagnetic Damper for Vibration Control of a Transmission Shaft

Abstract

The paper reports work on a feasibility study of an electromagnetic damper for vibration control with specific reference to a simulation of a marine propulsion system with turbine shaft, flexible power transmission shaft and primary pinion shaft. Control of the vibrational behaviour was achieved by an electromagnetic damper at a point in the span, and the experiments confirm the possibility of controlling the behaviour of a simulated marine propulsion system by contactless electromagnetic damping.
