Sandwich type ring rib cylindrical shell structure and technique thereof

Abstract

The invention relates to a sandwich type ring rib cylindrical shell structure and technique thereof. The sandwich type ring rib cylindrical shell structure comprises an outer shell, an inner shell is coaxially arranged in the outer shell, a sandwich layer is formed between the inner shell and the outer layer, a lower end close plate is arranged on the lower portion of the sandwich layer, upper end close plates are equidistantly arranged on the upper portion of the sandwich layer, cavities are formed among the upper end close plates, isolating strips are disposed in the cavities, each cavity is separated into two openings via the corresponding isolating strip, and rib web plates are further equidistantly disposed on the periphery of the outer shell, and are connected with a rib panel. The sandwich type ring rib cylindrical shell structure and the technique thereof can meet underwater noise reduction, but also improve underwater bearing ability.

Description

technical field [0001] The invention relates to the field of deep-sea pressure-resistant structures, in particular to a structure of a sandwich-type ring-ribbed cylindrical shell and a process method thereof. Background technique [0002] With the development of deep-sea equipment technology, underwater engineering structures need to meet certain requirements for their underwater noise reduction performance while increasing their diving depth. In order to meet its underwater noise reduction, the existing technology usually adopts the method of increasing the plate thickness or using materials with high yield ratio. Although the increase of the diving depth is realized, the noise reduction requirement cannot be met, and there are the following shortcoming: [0003] (1) After the plate thickness is increased, the self-weight of the structure is increased, which causes the loss of reserve buoyancy. [0004] (2) Materials with a high yield ratio have poor plasticity, making it...

In order to meet its underwater noise reduction, the existing technology usually adopts the method of increasing the plate thickness or using materials with high yield ratio. Although the increase of the diving depth is realized, the noise reduction requirement cannot be met, and there are the following shortcoming:

[0003] (1) After the plate thickness is increased, the self-weight of the structure is increased, which causes the loss of reserve buoyancy

[0004] (2) Materials with a high yield ratio have poor plasticity, making it difficult to ensure the safety of underwater engineering operations
