An underwater vibration isolation and sound insulation cabin section structure suitable for a UUV propelling device mainly comprises a rectification cabin body, a tail end cover, a vibration isolation mass block, a vibration isolation suspension, reamed hole screws, a damping sound absorption plate, a propelling motor and the like. The structure is used for arranging a UUV propelling device and greatly weakening noise radiated by the propelling device to a surrounding flow field through a shell, non-rigid connection between a propelling motor and a boat body structure is achieved mainly through a vibration isolation suspension, direct sound production of the propelling motor is isolated through a vacuum layer of a rectification cabin, a vacuum shell is supported through a vibration damping mass block, and vibration isolation is achieved. The damping sound absorption plates on the inner wall face of the fairing attenuate sound wave energy and restrain vibration of the inner wall face. The structure is simple and reliable, and the vibration isolation and sound insulation effects are good.
一种适用于UUV推进装置的水下隔振隔声舱段结构,主要包括整流舱体、尾端盖、阻振质量块、隔振悬架、铰制孔螺钉,以及阻尼吸声板、推进电机等;该结构用于布置UUV推进装置并大幅度削弱推进装置通过壳体向周围流场辐射噪声,主要通过隔振悬架实现推进电机与艇体结构之间的非刚性连接,利用整流舱体的真空层隔离推进电机直发声,通过阻振质量块支撑真空壳体并隔振,通过整流罩内壁面上的阻尼吸声板衰减声波能量并抑制内壁面振动。本发明结构简单可靠,隔振、隔声效果好。
