Embodiment Construction

[0043] In order to make the content of the present invention more obvious and understandable, the present invention will be described in detail below in conjunction with specific embodiments.

[0044] A method for preparing a frame-type raft or a base using composite materials includes the following steps:

[0045] Step 1: Structural decomposition of raft frame or base

[0046] According to the overall structure of the raft or the base, the structure is decomposed into four parts: the upper panel, the lower panel and the transverse and longitudinal ribs. Among them, the transverse and longitudinal ribs include multiple transverse ribs and longitudinal ribs. The connection between the longitudinal ribs and the lower panel and the transverse and longitudinal ribs are all "T"-shaped splicing, and the connection between the transverse ribs and the longitudinal ribs is the "ten"-shaped splicing, which is finally decomposed Plan, the decomposition plan includes the number and size of the ...

Abstract

The invention discloses a method for preparing a frame-type raft frame or base from composite material. The method comprises 1, raft frame or base structure disassembling, 2, composite material partitioned structure molding and demolding, 3, partitioned molded structure machining, 4, partitioned structure preassembling, 5, adhered surface roughening, 6, partitioned structure bonding, 7, binding transition zone filling and connection zone strengthening layer molding, and 8, opening processing and surface conditioning. The frame-type raft frame or base prepared through the method has the advantages of high dimensional precision, high strength, high rigidity, light weight, good fatigue resistance, good damping performances and obvious vibration damping effect.

Description

Technical field [0001] The invention belongs to the technical field of composite materials, and specifically relates to a method for preparing a frame-type raft or a base by using composite materials. Background technique [0002] Mechanical noise is one of the three major noise sources of ships. Due to the numerous types of mechanical equipment on the boat, they are distributed in all cabins of the boat, and mechanical noise is the main noise source for submarine concealed navigation conditions. Therefore, controlling mechanical noise is one of the main contents of vibration and noise reduction work. At present, the control of mechanical noise mainly includes two measures: controlling the vibration level of equipment and adopting vibration isolation technology. Due to the limited potential for controlling low-noise equipment and unable to meet the stealth requirements of ships, the vibration control of the transmission path is very important. The development of vibration isolat...
