STRUCTURE BORNE NOISE PREDICTION TECHNIQUES FOR DIESEL ENGINES

It is postulated that mathematical prediction of structureborne noise can be used to optimally design engine components. To this end, a description is given of a newly developed procedure that uses the finite element method to calculate the forced vibrations of the engine structure, and to consequently define the structural vibration characteristics of the engine and its mountings. The necessary preparations for the derivation of finite element models are described in detail. A comparison of measured and calculated structureborne noise from the surface of a truck engine demonstrates the accuracy of the prediction technique.
