Forced Vibration Analysis of Torsional Shafting with Gear-Branched Systems

In this study, an algorithm for the forced vibration analysis of a torsional shafting with gear-branched system is formulated by the transfer stiffness coefficient method. After developing a computer program for obtaing frequecy response of a torsional shafting with gear-branched systems by using the transfer stiffness coefficient method, the program was used for obtaing frequecy responses of a hige speed boat with a four stroke diesel engine and a gear system and a low speed ship with a two stroke diesel engine and two gear systems. The accuracy of the present algorithm is confirmed by comparing with the results of the free vibration analyses for the same shaftings.
