Abstract

Some basic equations for the acoustic modal analysis of a car cavity, based on the finite element method are presented. Also equations for the acoustic pressure determination in the case of vibrations of car body parts are derived. A computer program is developed and applied to the analysis of the automobile 'Zastava 101'. From the results obtained, conclusions are drawn about the influence of some changes of the car body geometry on acoustic characteristics, as well as those corresponding to the pressure distribution due to the vibrations of the roof, floor, front and rear windows. Results can have a practical value in car design.
