The Use of Finite Element Techniques to Predict Engine Vibration 820436

This paper presents structural analyses performed on an in-line, four-cylinder, two-liter automotive diesel engine for vibration reduction purposes. Both finite element modeling and experimental structural analysis were performed on the existing design. After applying both of these methods to the same structure, the reliability of the structural model was established. The finite element model, which was constructed as simple as possible, could then be used for predicting the effect of design changes on the structural behaviour of the block. A relatively simplified finite element model proved a very useful and accurate tool.
