A new design project of the line feed structure for large spherical radio telescope and its nonlinear dynamic analysis

Abstract A new design of the line feed structure for a large spherical radio telescope (LSRT) is presented in this paper. Integrated mechanical, electronic, optic and automatic control technologies are employed to make considerable improvement upon the Arecibo spherical radio telescope in Puerto Rico, U.S.A. Nonlinear dynamic analysis of the suspended cable system was carried out with some sensible results that could be useful to the real engineering of LSRT.
