Corrugated cylindrical pressure-resistant shell and forming device and method thereof

Abstract

The corrugated cylindrical pressure-resistant shell is formed by sequentially sleeving an inner cylinder, a middle cylinder and an outer cylinder at intervals, the inner cylinder and the outer cylinder are each of an axial corrugated cylinder structure, the outer side wave crests of the inner cylinder and the inner side wave troughs of the outer cylinder are tightly attached to the middle cylinder to form a supporting structure, and the portion between the inner cylinder and the middle cylinder and the portion between the middle cylinder and the outer cylinder are filled with composite materials; the invention further discloses a forming device and a forming method of the corrugated cylindrical pressure-resistant shell. The technical problems that in the prior art, a common cylindrical pressure-resistant shell is poor in mechanical property, the inner space is sacrificed due to the fact that reinforcing ribs are added, the bearing capacity is poor, and the safety performance is low can be solved. And the liquid resin and the nano composite material are added, so that the pressure resistance of the annular corrugated cylindrical pressure-resistant shell is enhanced, the weight can be reduced, the overall mass can be reduced, and the noise reduction effect is achieved.

Description

technical field [0001] The invention relates to the field of submersibles, in particular to a corrugated cylindrical pressure shell and a forming device and method thereof. Background technique [0002] With the continuous research in the marine field, there is less and less space for us to explore. The corresponding exploration of the deep sea is particularly important. With the continuous improvement of the diving depth, the pressure shell is an important part of the submersible. The material properties of the shell and the research on the manufacturing process need to constantly put forward new requirements to further increase the critical pressure of the pressure shell and provide a reference for the structural optimization design of the submersible. At the same time, the pressure-resistant shell is a thin shell structure that withstands hydrostatic pressure. It requires good mechanical properties, space utilization in the shell and meets ergonomic requirements. Its weig...

AI Technical Summary

Problems solved by technology

The currently known pressure hulls used in the deep sea have the following defects: the traditional cylindrical pressure hull has poor mechanical properties, and reinforcement ribs are often required inside for reinforcement, sacrificing the internal space of the shell, the reinforcement ribs and the pressure hull The welding between them is easy to cause the welding deformation of the pressure shell, so that the mechanical properties of the material of the pressure shell are not fully utilized in the production process, and the internal stress cannot be effectively released, resulting in a decrease in bearing capacity and low safety
