Problems solved by technology

[0003] At present, the vibration and noise reduction measures for the base are to apply damping to the surface of the base, but the effect of damping on the surface of the base is very limited for the overall vibration reduction of the base structure

Abstract

The invention discloses a mixed type vibration and noise reduction pedestal structure. The pedestal structure comprises pedestal face plates, pedestal web plates, pedestal knee plates and square steel, and the pedestal is integrally of a welding structure. The pedestal face plates are horizontally arranged, the longitudinal web plates, the transverse web plates and the pedestal knee plates are perpendicularly welded to the lower pedestal web plate, the pedestal face plates are welded to the pedestal web plates and the pedestal knee plates, and the square steel is welded to the bottoms of the pedestal web plates and the pedestal knee plates. The pedestal web plates and the pedestal knee plates are made of high-manganese-based high-damping alloy steel with the damping rate being about 0.03,and the structures of the other parts are made of conventional structure steel for ships. A pedestal is integrally connected through a welding mode and is finally installed on a ship body structure through a welding mode.

Description

technical field [0001] The invention relates to a base structure of surface ship equipment, especially a base structure with high requirements for vibration reduction and noise reduction. Background technique [0002] The surface ship base is an essential structure to connect the ship hull and equipment. The vibration of mechanical equipment radiates noise to the hull structure and the outside of the hull through the base. For the ship as a whole, in order to reduce the underwater acoustic radiation noise caused by mechanical noise to the ship as a whole, it is generally necessary to put forward higher requirements on the vibration and noise source of mechanical vibration and the equipment itself, in order to reduce the vibration and noise from the source. When the vibration (noise) of the equipment itself is difficult to further reduce, it is generally required for the equipment vibration isolator to reduce the vibration and noise of the equipment (vibration source) to an ...
