In this paper we describe the estimation theory of sound power radiated from a circular plate with a solid shaft and a solid cylinder, which is a simple model of an aircraft gear blank. The forced vibration of the circular plate with a solid shaft and a solid cylinder was solved by assuming that the displacement of forced vibration is equal to the linear sum of the eigenfunctions of the displacements of the circular plate part and the cylinder part. Using the obtained result, the equations for calculating the frequency spectrum of the three important parameters for estimation-radiation loss factor, driving point mobility and total loss factor-were derived.
