Abstract
The influence of the pin/main bearing journal diameters and the counter weight orientation to crankshaft axial vibration were examined using a fully flexible finite element engine model. The simulation, performed with AVL/Excite, incorporates modal contributions of all interfacing engine components and enables the study of interactions among the components. The simulation successfully predicted crankshaft axial vibration and was validated by measurements. The correlated CAE model was used to study modifications in crankshaft pin and main bearing journal diameters and in the orientation of the crankshaft counter weights. Design direction on how to minimize axial vibration was provided.
