DETERMINING NOISE RADIATION OF A DIESEL ENGINE DUE TO BEARING EXCITATION USING ANALYTICAL AND EXPERIMENTAL TECHNIQUES
After having determined the noise generation of a diesel engine this paper presents static and dynamic finite element analyses, correlated with some experimental work, in order to achieve proper structural modifications and provide effective noise reductions. Several methods are presented. Modifications to the engine structure can either be made by using a bedplate or by means of local geometric adaptations which allow for each part of the block to be treated separately.
