Abstract
The invention provides a novel array surface array frame structure, which comprises a wall body, a darkroom, a reinforcing frame, an array surface array frame and a rotary table, wherein the darkroom, the reinforcing frame, the array surface array frame and the rotary table are positioned in the wall body; the array frame is of an aluminum framework skin structure, so that the weight is favorably reduced; the array frame has small self-weight, which is beneficial to reducing deformation and improving rigidity.
Description
Technical Field
The invention relates to a structural design form, in particular to a array surface array frame structure.
Background
The array frame is a specially designed structural frame, has the functions of installing and supporting the radiation antenna array to form a radiation field, provides a platform field for the maintenance of the radiation antenna array and the placement of radio frequency feed system equipment, and provides a working platform and a space for system installation, integration, debugging and maintenance for workers. The wavefront array frame tends to be large in size and mass due to the need for radius of curvature and surface area, which in turn leads to a weakening in stiffness. In order to improve the rigidity, the specifications of the section bars and the plates of the array frame are further increased, and finally the mass of the array frame reaches hundreds of tons, and the array frame can only be placed on the bottom layer, so that the placement space is limited.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a array surface array frame structure which is light in weight, high in rigidity and high in space utilization rate, can fully utilize the existing space, maximizes the curvature radius and the surface area of the array surface, and is light in overall weight and high in rigidity.
According to one aspect of the invention, the array surface array frame structure comprises a wall body, a darkroom, a reinforcing frame, an array surface array frame and a rotary table, wherein the darkroom, the reinforcing frame, the array surface array frame and the rotary table are all located inside the wall body, the reinforcing frame, the array surface array frame and the rotary table are all located inside the darkroom, the array surface array frame is fixed on the reinforcing frame, and the rotary table is located on one side of the reinforcing frame.
Preferably, the array frame is a spherical sector of revolution.
Preferably, the array frame of the array is arranged along the diagonal of the darkroom.
Preferably, the array frame is an upper aluminum framework skin structure.
Preferably, the skin is attached to the array frame by rivets.
Preferably, the stiffening frame and the front array frame are connected by welding.
Preferably, the reinforcing frame is a lattice frame structure.
Compared with the prior art, the invention has the following beneficial effects:
1. the radius of curvature is maximized. The array frame of the invention is arranged along the diagonal line of the darkroom, realizes the maximization of the curvature radius of the array frame of the array surface, solves the problem that the curvature radius of the array frame of the prior inverted or side-standing bowl type array surface is relatively small,
the problem of low space utilization rate;
2. the weight is light. By adopting the aluminum structure and the optimized design of the reinforcing frame, the quality of the array frame is only one tenth of that of a steel array surface array frame with the same specification;
3. the cost is low. By reducing the quality, the array surface array frame cost is obviously reduced compared with the existing design;
4. the rigidity is high. By adopting the aluminum material and the reinforcing frame, the array surface array frame has higher rigidity;
5. the adaptability is good. The invention has no special requirement on the bearing capacity of floors, and solves the problems that the prior array plane array frame can only be placed on the bottom layer, if the array plane array frame is not on the bottom layer, the design needs to be planned in advance at the beginning of the design of a laboratory, and otherwise, the array plane array frame cannot be additionally built at the later stage.
The array frame structure design form of the array surface has light weight, high rigidity and high space utilization rate, can fully utilize the existing space, maximizes the curvature radius and the surface area of the array surface, and has light overall weight and high rigidity. The array surface array frame solves the problems that the existing array surface array frame is large in mass, high in cost, limited in curvature radius, incapable of maximizing, and required to be arranged on the bottom layer, and incapable of being built in later period.
