ACOUSTIC BEHAVIOUR ANALYSIS OF ENGINE BLOCKS 790986

ABSTRACT

The acoustic behaviour of an engine block was analyzed employing the finite element method. The procedure for assessing the acoustic behaviour was incorporated into an existing general purpose finite element program. The results obtained in the analysis correlated well with those extracted from modal tests. It is therefore concluded that a minimum of hardware testing in combination with analytical methods can yield an efficient and reliable problem solution.
