In this report the longitudinal, torsional and two directions of lateral vibrations on the shaftings of large, low-speed, seven-cylinders, in-line marine diesel engines and a small, high-speed, ten-cylinders, V-type automobile diesel engine are calculated first by the 3 dimensional analysis of forced vibration using the transfer matrix method, which has been developed by the authors.<BR>Next, the calculated results are compared with the corresponding experimental results for investigating the characteristics of the 3 dimensional vibrations and also the adequacy of the analytical method.<BR>As a result of the comparisons of the calculated results with the measured results, the following conclusions are obtained;<BR> The calculated results are approximately similar to the measured ones. From this comparison, it can be assured that the use of this 3 dimensional calculation methods enables the estimation of the longitudinal, torsional and two directions of lateral vibrations, including the coupled vibrations, provided that the correct input data are specified.<BR> The characteristics of the forced vibrations of the large, low-speed, marine diesel engines and the small, high-speed, automobile diesel engine are partially made clear.
