Problems solved by technology

Although this solution solves the problem of the accuracy of the feed mechanism, the rope mechanism is a wind-sensitive mechanism that will generate relatively large vibrations. How to ensure the horizontal position balance of the feed secondary positioning mechanism becomes the key to realizing the accuracy of the feed mechanism
This feed positioning device is a wind-sensitive device, and its first three-order natural frequency is less than 1, which poses a great problem to the accuracy control of positioning

Abstract

The invention relates to a big radio astronomical telescope feed local platform self-balancing device with inhibiting vibration and self-balancing ability. It is made up of the upper platform, Hook ream-spring device, four supporting rods, connecting rod and low platform. The invention provides a self-balancing device to connect the first and second rank local devices. When the low platform vibrates, the Hook ream can adjust self and the spring has pretightening force which can accelerate the adjustment to balance the feed platform quickly and improve the precision of feed source location. So it can keep the balance of second location device of feed source to reach the precision of the feed source device.

Description

technical field [0001] The invention belongs to the scope of components of a feed source positioning platform of a large radio astronomical telescope, and in particular relates to a self-balancing mechanism mechanical structure of a feed source positioning platform of a large radio astronomical telescope capable of suppressing vibration and having self-balancing capability. Background technique [0002] Radio astronomy is a science that detects the electromagnetic radiation of cosmic celestial bodies to reveal the mysteries of celestial bodies. For more than 60 years, with the help of modern electronic technology, radio communication, and the rapid development of computer technology, radio astronomy technology and methods have made great progress. As the main detection tool of radio astronomy, the radio telescope has become an indispensable tool in the process of human exploration of the universe, research on environmental issues and military fields. It is precisely because ...
