Abstract

The invention provides an attitude adjusting method and hydraulic system for antenna testing. The system involves a platform hydraulic subsystem, a rotary platform, an erecting hydraulic subsystem, alevel gauge, a controller and a rangefinder; the rotary platform is installed on the platform hydraulic subsystem, the erecting hydraulic subsystem is installed on the rotary platform and used for erecting or lowering a tested antenna, and the rotary platform is used for driving the erecting hydraulic subsystem and the tested antenna to rotate in the horizontal direction; the level gauge is used for monitoring the platform hydraulic subsystem; the controller receives a monitoring result of the level gauge for monitoring and can control the platform hydraulic subsystem and the erecting hydraulic subsystem; and the rangefinder is used for measuring the distance between the tested antenna and an external test reference surface, and sending the measured distance to the controller, and the controller controls the platform hydraulic subsystem to adjust the distance between the tested antenna and the external test reference surface according to an external target requirement and the measureddistance. The system has the advantages of being high in adjusting precision and high in adjusting speed.

Description

technical field

[0001] The invention relates to an attitude adjustment method and a hydraulic system for antenna testing, belonging to the technical field of hydraulic transmission and direction control. Background technique

[0002] After the large-scale array antenna is assembled, it needs to enter the dark room for a month of various tests. Before the test, the antenna should generally be turned vertically by 90°, and it is necessary to ensure a high degree of parallelism between the antenna test array and the test reference plane to ensure the accuracy of the test data.

[0003] At present, the commonly used test method is to place the antenna under test horizontally on the test platform. When the test platform enters the darkroom, first use the spiral legs (3 or 4) to support the platform and basically level the platform, and then shake the ball The screw mechanism turns the antenna from a horizontal state to a vertical state, and finally manually adjusts the screw leg...
