ABSTRACT

This research aims at the problem of insufficient antenna accuracy caused by the self-weight. Taking the 10-meter diameter reflector antenna as example, we firstly analyze the structural characteristics of the antenna, model it by finite element method and analyzes its deformation, and optimize and improve the backframe structure according to its deformation law by mainly improving the connection and structure of its beam and radiation beam. hen changes the skin to carbon fiber material to reduce the self-weight of the antenna, and compares the original antenna (aluminium alloy for the skin) and the optimized and improved reflective surface deformation. This paper can provide a certain reference for the structural optimization design of medium and large reflective surface antennas, and also provide research ideas for the simulation of deformation caused by the self-weight of the antenna.
