Abstract

The invention discloses an elastic composite anti-vibration joint of a marine ventilation pipe. The elastic composite anti-vibration joint of the marine ventilation pipe is composed of a flange, an annular anti-vibration mass block, an intermediate anti-vibration mass block, an elastic rubber tube and a superfine fiber layer. One end of the elastic rubber tube and the ring-shaped anti-vibration mass block are connected by bolts through flanges and screw holes, and the other end is connected by two I-shaped elastic rubber tubes facing each other, and the middle stacked middle anti-vibration mass block is connected by bolts. Elastic rubber tubing and microfiber layers glued together. Among them, the ring-shaped anti-vibration mass block, the middle anti-vibration mass block and the elastic rubber tube can be combined freely according to the actual anti-vibration requirements of the ventilation duct, so as to achieve various anti-vibration effects. The invention can effectively reduce the vibration transmission between the excitation source and the pipeline system, and achieve the effect of damping the vibration of the ventilation pipeline system. The invention is applied to the field of ship ventilation ducts.

Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction, and relates to a vibration reduction structure, in particular to an elastic composite vibration resistance joint of a marine ventilation pipe. Background technique [0002] The air conditioning and ventilation system in the ship can improve the working and living environment of the crew on board. There are few large machinery in the superstructure of the ship, so some ventilation ducts connecting the cabins of the ship become the main source of noise in the upper cabins. There are a large number of ventilation ducts in a ship and they are widely distributed. Vibration can travel a long distance through the ventilation ducts, resulting in noise at the air outlet of the air-conditioning ventilation ducts. Ship noise is related to the safety of sailing, and also affects the health of personnel and the comfort of the environment. In recent years, with the vigorous de...
