Reduction of Engine Noise in the New Accord Using Hybrid CAE Technology

Article of Honda R&D Technical Review Vol.14 No.2

Summary

Hybrid CAE models were constructed for the 2003 Accord to reduce cabin noise induced from engine order vibration. The Hybrid CAE method utilizes a combination of two different approaches: numerical and experimental analysis. Targets for each system’s contribution to cabin noise were established on the basis of tests of the prototype during the initial stage of development. The achievement of these targets has significantly reduced engine noise in the new Accord.
