The invention provides stern rudder noise reduction equipment which comprises a housing arranged on the surface of a shell in a covering mode. The memory deformation part deforms along with the temperature change and has an initial state and at least one deformation state; the memory deformation part is arranged between the shell and the cover shell, one end of the memory deformation part is fixedly arranged on the surface of the shell, the other end of the memory deformation part is fixedly connected to the inner wall of the farthest end, away from the surface of the shell, of the cover shell, the memory deformation part is switched to a deformation state through thermal deformation, and the connecting end of the memory deformation part and the cover shell moves away from the connecting end of the memory deformation part and the shell; the distance between the farthest end, away from the surface of the shell, of the cover shell and the surface of the shell changes along with change of the shape of the memory deformation part. Multiple memory alloy is used as a memory deformation part to drive the housings to move, the heights of the housings outside the housing are changed, and the groove is formed between the two housings, so that the depth and the shape of the groove can be adjusted according to needs, different navigational speed requirements are met, and the stable noise reduction effect is maintained.

    本发明提出了一种艉舵降噪设备,包括罩壳,罩设在壳体表面上;记忆形变件,随温度变化发生形变且具有初始状态及至少一个形变状态;记忆形变件设置在壳体与罩壳之间,记忆形变件一端固设在壳体表面且另一端固接在罩壳远离壳体表面的最远端内壁上,记忆形变件受热变形切换到形变状态,并使记忆形变件与罩壳的连接端远离记忆形变件与壳体的连接端移动;罩壳远离壳体表面的最远端与壳体表面的间距随记忆形变件形状变化而变化;通过多重记忆合金作为记忆形变件来带动罩壳移动,使罩壳在壳体外部的高度发生变化,由于两个罩壳之间夹成沟槽,因此能够根据需要调整沟槽的深度及形状,从而适用于不同的航速需求,以维持稳定的降噪效果。
