Improvement of Engine Noise for the 2003 Accord Using Hybrid CAE Technology 2003-01-1427
Hybrid CAE technology combined numerical and experimental analysis is applied on a product development for the 2003 Accord to improve cabin noise caused by engine order vibration. A vehicle model by hybrid CAE is constructed with a complex of two numerical and experimental approaches. Targets for each system are established on the basis of tests and FE models of the prototype constructed in the planning stage of development. The achievement of these targets has significantly reduced engine noise in the new Accord.
