Damping device of shuttle tanker comfort superstructure and manufacturing method

Abstract

A damping device of a shuttle tanker comfort superstructure and a manufacturing method are disclosed. The damping device comprises transverse toggle plate type plate frames, the transverse toggle plate type plate frames are welded and fixed to a left board and a right board of a front bulkhead and a rear bulkhead of a superstructure, and a plurality of horizontal cross beams and reinforcing ribs are welded to the transverse toggle plate type plate frames. The method comprises the steps that the transverse toggle plate type plate frames are positioned on a jig frame according to a drawing, and the positioning size of the reinforcing ribs and the position of the horizontal cross beam are marked on the transverse toggle plate type plate frames; the horizontal cross beam is welded to the transverse toggle plate type plate frames according to a scribing position; the reinforcing ribs are welded to the transverse toggle plate type plate frames, and the ends of the reinforcing ribs are directly welded to the horizontal cross beam; and after the damping device is integrally welded, the damping device is integrally hoisted and welded to the front and rear bulkheads of the superstructure. The damping device is simple and reasonable in design, remarkable in damping effect and capable of effectively reducing superstructure vibration power transmission so that the purposes of damping and noise reduction are achieved, meanwhile, the stability of a hull structure is ensured, and the comfort level of personnel is improved.

Description

technical field [0001] The invention belongs to the technical field of ship vibration, and relates to a vibration reduction method for a ship topside area, in particular to a vibration reduction device and a manufacturing method for a comfortable topside structure of a shuttle tanker. Background technique [0002] During the sailing process of the ship, the main engine, engine, propeller, side thruster and some auxiliary mechanical equipment will generate a lot of power during normal operation. When the excitation frequency is very close to the natural frequency of the ship structure, the hull structure will respond, thereby resonate together. [0003] The harm that resonance will bring to the ship is as follows: 1. The hull structure is deformed or damaged due to resonance, which affects the safety of the ship; 2. Reduces the use accuracy and life of equipment and instruments; 3. Affects comfort, endangers the health of the crew, and affects work efficiency. [0004] The ...
