A large-scale structural-acoustic analysis using sub-space superposition, in which a cavity is divided into several acoustic fields has been developed.This system uses a transfer-function mehtod to solve the acoustics efficiently.By solving simultaneous equations using the Gaussian-elimination method for each pair of neighboring acoustic sub-fields in sequence, calculation time and memory requirements are reduced.Calculation accuracy is the same as when calculating the entire acoustic field without dividing it.We created a closed acoustic model (a cavity model) and used it to numerically simulate acoustics.The simulation results show that the developed large-scale structural-acoustic analysis effectively reduces calculation resources.
