In this paper, a multi-piece parallel cantilever plate is taken as a model to study the fluid-solid coupling vibration characteristics of a parallel structure theoretically. The theoretical expression that is convenient for analysis and calculation is deduced and the calculation and experimental verification are carried out. The results show that the method of analysis is correct, which is of practical significance for the analysis of the complete fluid-structure interaction problem of the actual hydraulic structure.
