Problems solved by technology

[0003] At present, the conventional main load-bearing structure of spaceborne or airborne radar antennas is mainly a metal structure mounting plate or a honeycomb plate. The metal mounting plate is too heavy and sometimes cannot meet the heat dissipation requirements; although the honeycomb plate is lighter than the metal mounting plate, The honeycomb panels with embedded heat pipes can also meet the heat dissipation requirements, but the structural rigidity of traditional honeycomb panels is difficult to meet the requirements of the mechanical environment in some cases where U-shaped heat pipes need to be embedded and the system layout is limited.

Abstract

The invention discloses a main load-bearing structure and a radar antenna device, comprising a frame, an active mounting plate and a bracket; the frame includes a frame body and a partition, the frame body is an internal hollow frame structure, and the frame body internally fix the partition; the active mounting plate includes a main mounting plate and a reinforcement structure, the reinforcement structure is fixed on the bottom surface of the main mounting plate, the bottom surface of the main mounting plate is fixed on the upper surface of the frame main body, the The reinforcement structure extends into the frame body, and one side of the reinforcement structure is fixedly connected to the side of the partition; the side of the bracket is fixed to the inner wall of the frame body, and the top surface of the bracket is connected to the bottom surface of the main mounting plate. The advantage of the present invention is that the main load-bearing structure also improves the rigidity of the main load-bearing structure under the premise of satisfying the light weight and heat dissipation performance, which can effectively solve the lightweight, heat dissipation and rigidity of the main load-bearing structure of the radar antenna the contradiction between.

Description

technical field [0001] The invention relates to the technical field of radar antennas, in particular to a main bearing structure and a radar antenna device. Background technique [0002] For radar antennas used on spaceborne or airborne platforms, due to the limitations of the platform on weight, volume, heat dissipation and the requirements of the mechanical environment, it is determined that the corresponding radar antenna must have high integration, light weight, high strength, and high thermal conductivity. specialty. The main load-bearing structure in the radar antenna is the main installation carrier and function realization carrier of each stand-alone unit and module inside the antenna. It occupies a considerable part of the weight of the entire radar antenna, and the rigidity of the main load-bearing structure seriously affects the assembly of the stand-alone unit on it. 1. The situation of module vibration and stress. For example, Chinese Utility Model Patent Publi...
