THEORETICAL AND EXPERIMENTAL STUDY OF THE STRENGTH FATIGUE OF A DIESEL ENGINE CRANKSHAFT

A numerical and experimental analysis carried out on the fatigue resistance limits of the crankshaft of a marine diesel engine is discussed. Because of the complicated geometry of the crankshaft, a three-dimensional finite element analysis was used to determine the stress distribution under different boundary and load configurations. Likewise, a two-dimensional model of the crankshaft was composed. Comparison of its stress concentration data with the three-dimensional model showed a negligible difference. The calculations from the models and the results of the experiments showed good agreement between the values obtained. It is therefore possible to rely on the numerical results of a plane model in determining the stress concentration values of a crankshaft. Considerable savings in calculation times and crankshaft testing costs may thus be realized.
