Summary. This article describes the overview of crankshaft analysis of a medium speed diesel engine. Crankshaft analysis includes static analysis, crankshaft dynamics, bearing analysis, gear analysis, and stress & fatigue analysis, the latter being in main focus in this article. AVL Excite Power unit is used for multibody dynamics and Abaqus for finite element analysis.

Summary. Simulation of the gear train is an important part of the dynamic simulation of the power train of a medium speed diesel engine. In this paper, the advantages of dynamic gear wheel simulation as a part of the flexible multibody simulation of a complete power train are described. The simulation is performed using AVL EXCITE Power Unit.

Summary. This article describes the dynamic design of W4L20 VEBIC Genset, which consist engine, generator and baseframe. The engine creates the main excitations of the system. The eigenmodes of the Genset have to be adjusted by modifying the baseframe dimensions, so that the excitations are not in resonance with the eigenmodes. Eventually a feasible design has been found and shortly presented.
