摘　　要：双层隔振系统广泛应用于车辆、船舶、机械等行业。船舶机械设备振动通过隔振装置传递到船体结构进而向水下辐射噪声,建立基于潜艇圆柱壳舱段的典型动力设备双层隔振系统模型,研究了筏体结构、基座结构等参数对隔振系统、隔振性能的影响规律。筏体结构对圆柱壳舱段的动力设备,在一定频率下隔振性能影响明显,安装阻振结构可进一步提高系统的隔振性能,安装阻振质量后,在0~1 000 Hz频段隔振系统的平均振级落差提高了0.2 dB。合适的阻振质量安装位置在900~1 000 Hz最大可提高系统的隔振性能7.3 dB。研究成果可为舰船的动力设备设计提供借鉴。Double-layer isolation systems are widely applied in vehicles,vessels,and mechanical industries.Vibrations of shipbuilding machinery are transmitted to the hull structure via the isolation device,then radiated into underwater noise.A typical dynamic equipment double-layer isolation system model based on the cylinder shell section of submarines is estab-lished,and the influence rules of float structure and base structure parameters on the isolation performance of the isolation system are studied.Research results:the float structure has a significant effect on the dynamic equipment isolation perform-ance of the cylinder shell section at certain frequencies.The installation of an anti-vibration structure can further improve the isolation performance of the system.After installing anti-vibration mass,the average wave level difference of the isolation system increased by 0.2 dB in the 0~1000 Hz frequency band.The appropriate anti-vibration mass installation location can improve the system's isolation performance by up to 7.3 dB between 900 and 1000 Hz.These research results can provide reference for the design of ship's dynamic equipment.
