Abstract

The invention discloses an adjustable damping device for a mobile satellite antenna, which comprises a bottom plate and a top plate, the bottom plate is fixedly connected with the mobile carrier, the top plate is rotatably connected with the antenna frame of the mobile satellite antenna, and a plurality of The shock absorbers located in different directions are characterized in that the vibration damping amplitude adjustment mechanism is set on the top plate, the first acceleration sensor is fixed on the bottom plate, the second acceleration sensor and the controller are fixed in the antenna frame, the first acceleration sensor and the The second acceleration sensors are respectively electrically connected to the controller. The advantage is that the vibration damping amplitude adjustment mechanism adopts closed-loop automatic control, which can effectively avoid the natural frequency and prevent antenna resonance. At the same time, it can also meet the differentiated requirements of customers, and always maintain excellent tracking and sending and receiving indicators in various environments.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to an adjustable vibration damping device for a mobile satellite antenna. Background technique [0002] The mobile carrier satellite communication system is actually moving the satellite communication earth station to the mobile carrier. The mobile carrier satellite communication is a development direction of satellite communication. Real-time data exchange is becoming more and more common. [0003] During the movement of the carrier, the vibration of the overall or local structure will be caused. In the actual use environment, the mobile satellite antenna will be located in a high and unobstructed position and installed on the support frame, which will further amplify the vibration amplitude and affect the tracking and sending and receiving indicators of the satellite antenna. [0004] In order to reduce the influence of external vibration on the satellite antenna, a v...
