| 英文摘要: |
| This paper aims at investigating the effectiveness of squeeze oil film in suppressing the longitudinal vibration of propulsion shaft systems through a novel integral axial squeeze film damper (IASFD). After designing the IASFD, a propulsion shafting test rig for the longitudinal vibration control is built. Longitudinal vibration control experiments of the propulsion shafting are carried out under different magnitude and frequency of the excitation force. The results show that both IASFD elastic support and IASFD elastic damping support have excellent vibration attenuation characteristics, and can effectively suppress the longitudinal vibration of the shaft system in a wide frequency range. However, IASFD elastic damping support has a more significant vibration reduction effect than the other supports, and increasing the damping of the system has obvious effect on reducing the shafting vibration. For an excitation force of 45N, the maximum reduction of the vibration amplitude is 89.16%. Also, the vibration generated by the resonance phenomenon is also significantly reduced. |
