| Abstract: | The empirical formulas for calculating torsional vibration damping coefficient of marine engine are gathered and discussed. A new empirical formula is proposed as a result of the investigation so that the damping coefficient per cylinder of low speed and long stroke marine engine can be directly determined. Several examples of calculation indicate that the error rate of the empirical formula is very small. |
