Abstract

The invention discloses a large radio telescope with an active displacement type cable net knot supporting structure. The large radio telescope comprises a plurality of main cable knot discs, the main cable knot discs are connected through inhaul cables and are overall combined to form a spherical main cable net, joint bearings are arranged at the connecting positions of the inhaul cables and the main cable knot discs, and in the cable net displacement process, the inhaul cables carry out adaptive displacement through the joint bearings and the main cable knot discs to eliminate the additional bending stress of the connecting positions. The large radio telescope can effectively relieve the bending stress of a cable structure close to an anchorage device, and the overall reliability of the cable net structure is improved.

Description

technical field [0001] The invention relates to a large radio telescope with an active displacement type cable net node support structure. Background technique [0002] The Five-hundred-meter Aperture Spherical Telescope (FAST--Five-hundred-meter Aperture Spherical Telescope) project was approved by the National Development and Reform Commission on July 10, 2007, and belongs to the national "Eleventh Five-Year" major scientific engineering project. The telescope has extremely high detection sensitivity and huge observation sky area coverage, and it will provide mankind with a lot of opportunities for new discoveries and new breakthroughs after it is put into use. At the same time, it will extend my country's deep space exploration and communication capabilities to outer planetary space, and has the ability to become a strong ground support for my country's future deep space exploration plans. [0003] The telescope uses a flexible cable net as the supporting structure of th...
