摘　　要：通过分析某气垫船左舷垫升风机的设计特点,选择关键位置开展振动响应频谱测量,分析不同测点位置、不同转速条件下测点的振动响应。采用有限元方法分析单舷垫升风机的固有频率和振型,研究影响垫升风机振动的主要因素。在此基础上,提出降低垫升风机振动的措施,并基于试验评估实际降振效果,其可作为气垫船垫升风机设计的技术参考。By analyzing the design characteristics of the port side lift fans of the air-cushion vehicle, the key position is selected to carry out the vibration response spectrum measurement, and the vibration response of the measurement point at different measurement points and different speeds is analyzed. The finite element method is used to analyze the natural frequency and vibration mode of the single side lift fans, and the main factors affecting the vibration of the pad lifter are studied. On the basis, the measures to reduce the vibration of the lift fans are proposed, and the actual vibration reduction effect is evaluated based on the test, which can be used as a technical reference for the design of the lift fans of air-cushion vehicle.
