The coupled vibration of structure-acoustic system is a general problem in engineering,its theory and numerical value method is very important to the interior noise reduction for vehicle and ship.The relationship of left eigenvector and right eigenvector is deduced based on the finite element model of coupled structure-acoustic system and prove that the eigenvalue of this system is real number although the coupled matrix is non-symmetry.The eigenvalue of cylinder shell coupled with interior acoustic field and hexahedron coupled with interior acoustic field are performed by used of complex Lanczos method as examples.The results show that the eigenvalue is really real number.This research clarify further the feature of eigenvalue and will advance its application in engineering for coupled structure-acoustic system.
