abstract

The paper presents results of research on the transmission of fluid borne noise in reservoir filled with fluid. This type of transmission of vibrational energy in the fluid occurs in fluid power units, in which hydraulic pumps are immersed in the liquid in the tank i.e. in the vertical mounting of the electric motor on the reservoir. There are vibrating elements submerged in the fluid like pumps, pipe elements, filters, etc. Due to the vibration of these elements fluid borne noise will be generated which will be transmitted to the tank structure. The transmission of fluid borne noise is dependent on natural frequencies of the tank structure. Based on model investigations, the mechanism and factors influencing the intensity of transmission of fluid borne noise in a reservoir were presented. The results of simulations with FEM were compared with the results of experimental investigations.
