This paper presents an analytical study of a coupled vibration of two discs which face with each other in a fluid-filled annular vessel. Simple theoretical formula are obtained by assuming that the discs have a small width compared with the outer diameter of the annular vessel. In this case, the motion of the disc is approximated to be uniform in the radial direction. It is assumed that the fluid has no viscosity, no compressibility and no flow through the gap between the disc and the vessel wall. This paper discusses only the vibration of diametral modes with identical node number in the two discs. The formulae obtained show that two coupled frequencies appear for each number of the node. The effects on the frequencies of the disc thickness and the fluid layer are discussed in detail.
