Preliminary Results on the Development of an Aircraft Cabin N&V Simulator 2010-36-0546
In order to generate in-flight acoustic and vibration fields
inside an aircraft cabin mock-up, an N&V simulator was
developed. The preliminary work on the development, setup and
characterization of the N&V simulator will be presented.
Firstly, an overview of the system will be given, including the
desired input signals, followed by the presentation of the control
software, which was developed to simplify the operation of the
system by end users during routine testing. Secondly, the set-up
strategy to adjust the reproduction of levels and spectrum of both
acoustic and vibration fields will be presented, along with
comparative vibroacoustics results between the mock-up and original
in-flight recordings. Finally, a discussion on different methods
for adjusting the simulator reproduction by means of optimal
filtering is made, and further developments are presented.
