A hybrid method for modelling engine noise

Dixon, J.D., Baker, J.M. and Challen, B. (2000) A hybrid method for modelling engine noise In European Conference on Vehicle Noise and Vibration, Institution of Mechanical Engineers Headquarters, London, UK, 10-12 May 2000. IMechE, Professional Engineering Publishing., pp. 107-123.

Record type: Conference or Workshop Item (Paper)


Methods for modelling the radiated noise of automotive engines have become increasingly sophisticated over the past 30 years. However, the ever reducing development time demanded by vehicle manufacturers has meant that many of the current modelling methods fail to deliver results in time to be of assistance in such development. This paper proposes a simple hybrid modelling approach that has significant speed advantages. The power of current techniques (e.g. Finite Element Methods) is still retained for relative predictions, but the all important absolute levels are determined using an empirically based parametric noise generation model.
The emphasis of the paper is on the creation of this core parametric noise generation model although examples are given of how the more traditionally based peripheral or satellite models are incorporated.
Results for a parametric model of a state of the art HSDI engine are presented and the relatively minor anomalies seen in these results are discussed.
