A theoretical analysis of the propeller and/or engine-induced axial vibration of the propulsion system at the design stage is mainly justified for the following reasons: the ability of this vibration to excite structural vibration of, for example engine room double bottom and other structures as well as local and fundamental vibration of the superstructure through the thrust block reactions. The ability of this vibration to excite the propulsion machinery itself, i.e. engine, reduction gear, etc. The calculation of the different modes of shaft vibration are described, and some examples showing the interaction between the shafting and the surrounding structure are presented.
