A New Design Project of the Line Feed Structure For Large Spherical Radio Telescope and Its Nonlinear Dynamic Analysis

摘要

An evolutionary design of the line feed structure for the large spherical radio telescope is presented. In the new design, the integrated mechanical, electronic and topic technologies are employed to make some improvement about the Arecibo spherical radio telescope in America. As one part of the researching work. nonlinear dynamic analysis of the cable systme is carried out with some sensible results.
