Abstract :
The 3-D models of the cylinder block of 4D25G Diesel Engine, were modeled with Pro/Engineer and reasonably simplified. Elements were applied to mesh 3-D geometric models, and then the FEM model was constructed. Using the model, a modal analysis was done to get the basic vibration mode and the nature frequency of the cylinder block. Through analysis for results, we can learn dynamic characteristic of the cylinder block. It can provide the direction in which the vibration and noise could be further reduced through the structural improvement.
