The efficiency of vibro-acoustics analysis has been a major concern in dealing with large-scale vibro-acoustic systems such as a passenger car, owing to that its finite element model usually contains a huge amount of degrees of freedoms (DOFs) because of its geometrical complexity. To speed up the analyses while keeping desired computational accuracy, this paper develops a modified component mode synthesis method which emphasizes on the coupling techniques of non-conforming structural-acoustic interfaces. The non-conforming interfaces are introduced intentionally by considering that acoustic cavities are usually not necessary to be discretized as finely as structures to deliver equally accurate results. A radial basis function-based, master-slave interpolation formulation is developed to connect the physical field variables across the boundaries of substructures, while the left internal DOFs in each substructure are condensed to fewer modal variables. The computational perfor-mances of the proposed method are verified through a passenger car model.
