【Abstract】 A concept of the Huge Flexible Stewart Platform is presented for the suspending cable structure of the large spherical radio telescopes feed system. The issue of the loosed flexible cable is emphasized and the criteria condition is also given, on the basis of which a general algorithm is developed to determine the maximum working angle of feed at its working position by utilizing non linear static equations. And the analysis of the feeds extreme working position and the maximum working angle of the large spherical radio telescope not only makes stable control possible, but also provides the necessary parameters for the design of high accuracy large spherical radio telescope.更多还原
