This paper describes the design procedure of torsional vibration dampers applied to diesel engine-generator systems for the reduction of shaft torsional vibration. Firstly, the torsional vibration analysis of diesel engine-generator systems is required to confirm the necessity of dampers. If necessary, we convert the multi-degree of freedom engine-generator shaft model into a single degree of freedom one using modal analysis. Finally, we use the optimum parameter theory having the exact solution for 2-degree of freedom systems to determine optimized damper parameters. The theory and procedure are verified by applying to an existing diesel engine-generator system as an example.
