The ship stern shaft bracket distributed active vibration absorption device comprises a ship body, a propulsion shaft system and a stern shaft bracket are symmetrically arranged on the left side and the right side of the ship body, the front half section of the propulsion shaft system is arranged on the inner side of the lower portion of the stern of the ship body, and the rear half section of the propulsion shaft system is arranged at the bottom end of the upper portion of the stern of the ship body through the stern shaft bracket. Two groups of vibration absorption mechanisms are arranged on the deck, each vibration absorption mechanism comprises a plurality of electromagnetic actuators, and the electromagnetic actuators work independently; the electromagnetic actuators are divided into two groups and are arranged on a deck above the stern shaft brackets on the two sides, and the electromagnetic actuators suppress transverse vibration generated by the propulsion shaft system by generating vertical control force. The electromagnetic actuators are independent and work synchronously, and meanwhile, a transverse low-frequency vibration line spectrum of a stern shaft bracket and a broadband spectrum generated by surface force of a propeller are restrained, so that underwater low-frequency vibration sound radiation of a ship body is reduced.

    本发明公开了一种船舶艉轴架分布式主动吸振装置,包括船体,在船体左右舷对称设有推进轴系和艉轴架,推进轴系的前半段设在船体的艉部的下部内侧,推进轴系的后半段通过艉轴架设在船体艉部的上部底端,在甲板上设有两组吸振机构,吸振机构包括若干个电磁作动器,电磁作动器之间独立工作;电磁作动器分为两组布设在两侧艉轴架上方的甲板上,电磁作动器通过产生垂向控制力来抑制推进轴系产生的横向振动。电磁作动器之间独立、且同步工作,同时抑制艉轴架横向低频振动线谱和螺旋桨表面力产生的宽带谱,以降低船体水下低频振动声辐射。
