摘要
Abstract
A synmmetrical finite element model for structure-acousticcoupling analysis of the automobile passenger compartment is set up．Then， a dynamic substructure method is put forward based upon the symmetrical model，which can be used to integrate the influence of the interior decorations and accessory structures of the passenger compartment．In the concrete an interior decoration or accessory structure is regarded as a pair of substructure／subspace respectively in the primary structure domain and interior acoustic fluid space．And the influence of the interior decorations and accessory structures is brought into the symmetrical model so as to achieve a high accuracy result of the finite element analysis．Finally，an example for the passenger compartment of a saloon car is solved in order to validate the correctness of the method given in this paper．关键词
