Abstract

The invention discloses a novel two-freedom-degree parallel ship-borne radar antenna stabilizing platform. The novel two-freedom-degree parallel ship-borne radar antenna stabilizing platform comprises an antenna, a movable platform, a machine seat, and four motion branch chains which are connected with the movable platform and the machine seat, wherein the antenna is fixedly connected with the movable platform; each motion branch chain consists of a lower connecting rod, a middle connecting rod and an upper connecting rod; the four motion branch chains are connected with one another through four coupling connecting rods and a central connecting rod; one end of each coupling connecting rod is fixedly connected with the middle connecting rod of the corresponding motion branch chain; the other end of each coupling connecting rod is connected with the central connecting rod through a rotating pair; the axes of the four rotating pairs formed by the four coupling connecting rods and the central connecting rod are overlapped with one another. According to the novel two-freedom-degree parallel ship-borne radar antenna stabilizing platform, azimuth angle adjustment and pitch angle adjustment of a radar antenna can be realized; the novel two-freedom-degree parallel ship-borne radar antenna stabilizing platform has the advantages of being wide in angle adjustment range, high in rigidity, precision and dynamic performance, and the like.

Description

technical field [0001] The invention relates to a shipboard radar antenna stabilization platform, in particular to a two-degree-of-freedom parallel shipboard radar antenna stabilization platform. technical background [0002] When a ship is traveling at sea, due to unstable factors such as wind and waves, the hull will sway and tilt, which has a great impact on shipboard equipment, especially shipboard radar antennas. The shipborne tracking radar antenna needs to ensure the relative attitude relationship between the radar antenna and the tracked target at all times. In order to ensure the stability of the radar antenna signal, it is necessary to offset the influence of the ship's sway on the radar antenna through a stable platform. Most of the existing shipboard stabilization platforms are series adjustment mechanisms. For example, the Chinese invention patent CN103760811A discloses a shipboard heavy-duty stabilization platform. Affected, the Chinese utility model patent CN...
