Numerical and Experimental Validation of Hybrid FE-SEA Method

This paper considers the problem of predicting the transmission of structure-borne noise through the structure. Two thin aluminum plates are point connected to a z-section frame via five point connections; the first plate is excited by spatially distributed (rain-on-the-roof) excitation and interest lies in predicting the transverse response of the second plate across a frequency range from 15 Hz to 1.5 kHz (the properties of the structure are listed in Table 1). The chosen structure is fairly simple, but demonstrates a number of problems that are commonly encountered when using existing vibro-acoustic analysis tools. The following sections of the paper discuss the analysis of the structure using finite element analysis (FE) and statistical energy analysis (SEA).
