Embodiment 2

[0043] refer to figure 1 , different from Embodiment 1, a method for making an annular pressure hull device suitable for a submersible, comprising the following steps:

[0044] S1: Cutting, cutting out the cut surfaces on both sides of the initial spherical structure of the spherical pressure vessel manufactured according to the requirements, so as to facilitate the subsequent connection and fixing of multiple spherical annular pressure vessels;

[0045] S2: According to the radius of the inner ring and the radius of the outer ring of the curved ring-shaped sphere, calculate the thickness of the curved ring-shaped sphere, and the thickness of the ring = the radius of the outer ring R-the semi-ring of the inner ring r, and select a suitable sphere according to the thickness of the curved ring ;

[0046] S3: calculate liquid pressure both P=ρgh according to the pressure of submersible in liquid;

[0047] p—liquid pressure (Pa)

[0048] ρ—liquid density—kilogram / cubic meter (k...

Abstract

The annular pressure-resistant shell device comprises hemispheres at the head end and the tail end and a middle multi-section bent annular structure, and the bending radius R of the middle multi-section bent annular structure and the length L of the annular structure need to be specifically distributed according to the actual sizes such as the pressure-bearing requirement of the submersible and the total length of the submersible. The bent annular structures are spherical, and tangent planes are arranged on the two sides of each bent annular structure, so that subsequent connection of the multiple bent annular structures is facilitated. The annular pressure-resistant shell is composed of hemispheres at the head end and the tail end and a plurality of bent annular structures, and due to the structural design, structural components can be reduced, the structural weight can be reduced, and the structural welding amount of the pressure-resistant shell of the submersible can be reduced; the weight and the welding amount of the submersible pressure-resistant structure can be reduced; meanwhile, the structural stress of the diving pressure-resistant structure can be improved; and the internal minimum stress level of the diving pressure-resistant structure is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of pressure-resistant hulls of submersibles, in particular to an annular pressure-resistant hull device suitable for submersibles. Background technique [0002] The design of the pressure-resistant structure is the key issue in the structural design of the submersible. In addition to meeting the requirements of the maximum hydrostatic pressure, the pressure-resistant shell of the submersible also needs to meet the requirements of the number of diving cycles, the maximum tank capacity, and the minimum weight. [0003] Although the current submersible pressure shell adopts T-shaped steel or spherical flat steel or Π-shaped cylindrical shell reinforced with circumferential ribs, which can better meet the above requirements, but the increase in the diameter of the pressure shell, the traditional pressure shell structure Weight and welding requirements increase further. Contents of the invention [0004] The p...
