摘要：

A fuel pump is one of the primary vibration sources of torpedoes because the strong structure vibration and fluid vibration come up unavoidably and transfer to the shell during the process of fuel pressurization. To decrease the pump's vibration, the professional hydraulic system simulation software AMESim was used to build a hydraulic simulation model for the fuel pump whose structure and work principle are very different from the standard swashplat pump. Meanwhile, setting up a dynamic pressure measuring system, the dynamic outlet pressure of the pump was tested and compared with the simulated output pressure. The comparison shows the model is accurate. The simulation about the output pressure, output flow and cylinder pressure corresponding to different distribution angle was performed further by applying the verified model. And an appropriate angle, which can both eliminate the peak pressure and hardly affect the outlet pressure and flow of the pump, was selected. A physical prototype with the satisfying angle was made under the guidance of the simulation. A contrast test shows the vibration of the improved pump is markedly lower than the unimproved one, and the maximum of the difference is about 5 dB. © 2017, Editorial Office of Journal of Vibration and Shock.
