Abstract In practical vibro-acoustic problems, the external excitation normally contains a certain frequency band
structure [1]. Therefore, it is needed to perform optimization under frequency band analysis. For sound
radiation problems caused by structural vibration, a topology optimization method for structural materials
is proposed based on the acoustic-vibration coupling analysis [2-6] and the frequency-band matrix
interpolation method [7,8]. By combining the advantages of FEM and BEM in structural and acoustic field
analysis, the accurate solution of the acoustic-vibration coupling problem is achieved. The structural
material interpolation model is established using the solid isotropic material with penalization (SIMP)
method, and the topological… More >
