Abstract:
A rectangular thin-walled box is used as a test problem for comparing the results obtained from finite element analysis (FEA), boundary element analysis (BEA), statistical energy analysis (SEA), and experimental measurement. The box structure is mechanically excited by a random point force generated by a vibration exciter. The structural acoustic coupling has been taken into account because there is a significant acoustical pressure load acting on structural surfaces of the box. Both structural and acoustic responses are investigated and good agreement is observed between the numerical and experimental results.
