A multi-plane pressure-resistant structure

Abstract

The invention belongs to the field of pressure-resistant structures, and particularly relates to a multi-plane pressure-resistant structure. The multi-plane pressure-resistant structure is formed by a multi-plane cylinder and multi-plane semispherical shells at the two ends of the multi-plane cylinder jointly, or is directly formed by two identical multi-plane semispherical shells. The multi-plane semispherical shells are shaped like a spherical shell overall. The surface of each multi-plane semispherical shell is formed by mutually splicing a plurality of second basic plane plates, and a certain plane included angle exists between every two adjacent second basic plane plates. In the connecting positions of one multi-plane semispherical shell with the multi-plane cylinder / the other multi-plane semispherical shell, smooth curved line transition is not adopted between the basic plane plates. The multi-plane pressure-resistant structure guarantees the pressure resistance, lowers the influence of transition sections between the cylinder and the spherical shells on the mechanical characteristics of the whole multi-plane cylinder shell structure, and has the advantages of being high in pressure resistance, simple in production process, short in manufacturing period, easy to produce on a large scale and the like.

Description

technical field [0001] The invention belongs to the field of compression structures, and more specifically relates to a multi-plane pressure-resistant structure, which reduces the impact of the transition section between the cylinder and the spherical shell on the entire multi-plane cylindrical shell structure while ensuring the pressure-resistant performance. influence on the mechanical properties. Background technique [0002] For equipment that needs to withstand high external pressure during work, such as aircraft, submarines, bullets, etc., the structure of the cylindrical shell has a crucial impact on its compressive performance. In order to enhance the external pressure resistance of the shell structure, there are usually two methods, one is to thicken the existing structure to enhance its own structural characteristics, and the other is to modify the existing structure to achieve enhancement through structural advantages The purpose of structural mechanical properti...

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides a multi-plane pressure-resistant structure, in which, through the design of the respective setting methods of its key components and their mutual connection and cooperation, the spherical shape can be fully utilized accordingly. The two different characteristics of the curvature change of the structure and the folding change of the multi-planar cylinder can have both the excellent structural characteristics of the spherical shell and the cylindrical shell, and it is no longer necessary to separate the cylindrical shell and the cylindrical shell in the actual manufacturing process. A transition section is set between the hemispherical shells, thereby effectively avoiding defects such as the overall performance degradation of the multi-plane cylindrical shell structure caused by the existence of the transition section, so it is especially suitable for equipment such as submarines, aircraft or projectiles
