Vibration Transmission

The dynamic characteristics of a structure are modified considerably when it is immersed in a dense fluid. Dynamic interaction between fluid and structure includes the phenomenon of Fluid Structure Interaction (FSI). In the present study, transmission of vibration between two parallel plates partially immersed in a fluid is investigated considering FSI. It is assumed that the plates are clamped along their edges and the fluid is bounded between the two parallel plates to form a rigid rectangular container. Excitation of one plate by an impact load results in the response of the opposite plate. An experiment was conducted and the results were compared with the three-dimensional Finite Element Method (FEM) analysis using CAST3M. Wet dynamic displacement, the frequency of vibration of the two parallel plates with variation in the fluid level are the parameters considered in the present study. Effect of liquid free surface and viscous damping are considered. A benchmark validation from literature has been presented for the free vibration of immersed cantilever plate using CAST3M. It is observed that the damping ratio decreases with an increase in the fluid level and the displacement of the response plate increases. This study especially has been carried out towards the investigation of vibration transmission between structures partially immersed in the liquid sodium in Fast reactors. The objective of the present work is the numerical verification and experimental validation of the FEM model which would make it convenient while analyzing the vibration of immersed structures with FSI.
