Abstract

In recent years, new type main engines which have long stroke slender shaft have appeared. Because of the softness of the new engine shaft system, torsinal, axial and bending vibrations are coupled together, and the vibrations are complicated and influenced to the vibrations of the engine room and the ship hull.
We have developed a vibration analysis by using Building Block Approach, which have some merit for countermeasure of vibration reduction, and comfirmed the accuracy compared with the actual ship measurement data.
