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 framed raft or foundation using composite materials, comprising the steps of:

[0045] Step 1. Structural decomposition of raft or foundation

[0046] According to the overall structural form of the raft or foundation, the structure is decomposed into four parts: the upper panel, the lower panel and the transverse and longitudinal ribs. The transverse and longitudinal ribs include multiple transverse ribs and longitudinal ribs, and the upper panel and the transverse The connection between the longitudinal ribs and between the lower panel and the transverse and longitudinal ribs is "T"-shaped insertion, and the connection between the transverse ribs and longitudinal ribs is "ten"-shaped insertion, which is finally decomposed The decomposition scheme inclu...

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 in particular relates to a method for preparing a frame-type raft or base by using composite materials. Background technique [0002] Mechanical noise is one of the three major noise sources of ships. Due to the large variety of mechanical equipment on board, they are distributed in all cabins of the ship, and mechanical noise is the main noise source of submarines in concealed navigation conditions. Therefore, controlling mechanical noise is one of the main contents of vibration and noise reduction. At present, there are mainly two measures to control mechanical noise by controlling the vibration level of equipment and adopting vibration isolation technology. Due to the limited potential of controlling low-noise equipment, it cannot meet the stealth requirements of ships, so the vibration control of the transmission path is very important. The development of vibration isolation ...
