Embodiment Construction

[0075] Below in conjunction with accompanying drawing 3- Figure 21 , taking the 140-hedron, 180-hedron, 240-hedron and 320-hedron as examples to describe the specific implementation of the metal reticulated radome of the present invention.

[0076] 1. Construction steps of spherical 140-hedron metal reticulated dome radome:

[0077] (1) Select the side length ratio M=1:0.65 to establish a 32-hedron variant plane primitive, such as Figure 5 Shown by the dotted hexagon;

[0078] (2) According to the requirements of random design elements, synchronously rotate the regular pentagon by a rotation angle α, obtain the intersection point on the rotating side of the pentagon as J, and make the intersection point connect with the midpoints D of the long sides of the primitive, and the new primitive formed is defined as Spherical reticulated shell non-distorted planar mutation primitives, such as Figure 5 indicated by the dotted line.

[0079] (3) On the plane mutation primitive, ...

Abstract

The invention discloses a method for quickly establishing a spherical antenna cover with a metal latticed shell structure and belongs to the crossing field of civil engineering metal latticed shell mechanics and electronic engineering. The method comprises the steps of firstly establishing a 32-face body and a variant of the 32-face body, selecting pentagonal synchronous rotation random element and establishing planer variation elements through pentagonal rotation angle control; adopting a geodesic projection method on the new planer variation elements to perform topological mapping transformation towards the external spherical surface of the variant of the 32-face body through the center of a variation element plane, a boundary center and a pentagonal center and performing random triangular spherical polyhedral main body establishment; finally giving spherical antenna cover whole topological structure design. The whole antenna cover is composed of shed face film plates and node base assembling members, the film plates with polyester film opening structures and the triangular metal frame structure design are combined with the antenna cover whole topological structure design, so that the metal antenna cover has good mechanical property and electromagnetic property and has very high wind and snow resisting capacity and a small radiation loss characteristic.

Description

technical field [0001] The invention relates to a rapid construction method of a spherical radome with a metal reticulated shell structure, which belongs to the interdisciplinary field of civil engineering metal reticulated shell mechanics and electronic engineering, and is based on the integration of topology, space geometry, structural mechanics, and electromagnetic radiation. The theoretical design and rapid construction method of the established triangular configuration metal reticulated dome structure radome. Background technique [0002] The metal reticulated radome has a very wide range of uses and can be used as a device for receiving remote sensing data from remote sensing satellites. For example, the radome of the Russian "Samara" Earth Remote Sensing Data Receiving and Processing Center can ensure accurate reception of remote sensing test data around the clock , to give mines, geological occurrence status and farmland and ocean monitoring results, so as to evaluat...
