Abstract

Generally, there are many kinds of pumps used on a ship, which play an obbligato role to assist the ship's running. However, due to the pump's own motor, it becomes a main vibration resource that may cause serious problems in local. If the above situation happened, it may cause local resonance even structural damage. Also, the bigger the pump's size is, the more serious the vibration is. Therefore, it is very important for researchers to estimate the vibrations situation of pumps accurately and avoid or reduce the probability of resonance. Based on a real marine pump-HHG8065, this paper did a vibration analysis by FEM (Finite Element Method) and compared the results with actual test. Finally, it gave a discussion on the estimation of pump and provided an improvement way to the vibration level.
