Abstract: The residue theorem is employed in the design optimization of the frequency averaged power injected into a linear second-order system. The dynamic behaviour of a vibrating structure is obtained with the finite element method and the frequency averaged input power into the structure is adopted as an objective function. The design sensitivity with respect to each structural element is computed by the adjoint variable method with consideration for the residue theorem. The proposed method highly enhances the computational efficiency of the optimization and the design of the optimization leads to substantial reduction of the radiated sound power from the structure.
