CAE Support to Woofer Installation in a Car
AES Convention 144 · Paper 420 · May 2018
Abstract
CAE support to the development of the audio system from an automotive OEM perspective is discussed, on the example of the development of the details of installation of a door woofer. For this application a loudspeaker model driven with electric voltage has to be integrated in the vibro-acoustic simulation. An example of an implementation of such a model is discussed and the accuracy of simulations is presented for the case of a woofer in free hanging door. It is further discussed in car models with different trim levels, from plane metal body with trimmed closures to fully trimmed body. Finally, the results obtained in a car model, with different variants of installation details of the woofer are presented and discussed.
