Hybrid SEA Modeling Scheme for Analysis of High-frequency Noise in Passenger Car

摘要

A hybrid SEA modeling method has been developed and applied to increase the accuracy of an SEA model for a passenger car. This paper will discuss the detailed workflow of the modeling method and the method employed to verify the accuracy of the model during development. In addition, to provide an example of the high level of accuracy of results, the paper will discuss a road noise (interior cavity sound pressure level) analysis conducted with a complete vehicle SEA model constructed using the method.
