Due to the particular geometry of the crankshaft of twostroke diesel engines and the rotational degree of freedom torsional vibrations may be calculated with a 1-D mathematical model, but all other kinds of vibrations have to be calculated with a 3-D model. This concerns also static problems. In this paper the influence of coupled vibrations on ship vibration is explained and illustrated with an example for axial vibrations and an example for external vertical forces and moments. Another example for the use of the 3-1 model is the calculation of crank deflection and jack load. It can be shown that such calculations are suitable for daily work.
