RESEARCH ON THE DESIGN AND VIBRATION ISOLATION PERFORMANCE OF A NEW LIGHTWEIGHT DAMPING BASE

  • 摘要: 为了减少船体振动与辐射噪声,采用声子玻璃和弧形衔接结构设计了一种新型轻质阻尼基座。然后用加速度振级落差表征其隔振性能,开展了水泵电机激励下的基座隔振性能试验研究, 结果表明阻尼基座在20\sim10 000 Hz的频率范围具有显著的隔振效果,相较于同尺寸钢制基座,其振动落差总级可达12.93dB。研究结果充分验证了本文设计的轻质阻尼基座具备高强度、高阻尼、宽频隔振的特点,在舰船机械设备等减振降噪领域具有广泛的潜在应用价值。

     

    Abstract: In order to achieve the purpose of reducing hull vibration and radiated noise, a new lightweight damping base has been designed by using phononic glass and arc connection structure in this paper. After the above procedures of design and preparation, we used the vibration level drop and vibration isolation test method to characterize and test the performance of vibration isolation for the damping base. The results show that the damping base has a significant vibration isolation effect in the frequency range of 20\sim10 000 Hz, and compared with the steel base with the same size, the total vibration drop can reach 12.93 dB. Finally, a clear conclusion is given that the lightweight damping base designed in this paper has the characteristics of high strength, high damping and wide frequency vibration isolation, so it has a wide range of potential applications in vibration isolation of equipment for marine machinery, vibration and noise reduction of vehicles, etc.
