Abstract

Abstract: The curve equation and its mechanics analysis of suspended-cable under the condition of end load are given. Then on the basis of it,the mechanical analysis of suspended-cable system for large spherical radio-telescope is studied, and procedures of the control for the orbit tracking movement of the line feed in large spherical radio-telescope are given. The validity of the results mentioned above is confirmed by means of computer simulations.

Key words: large spherical radio-telescope, orbit tracking movement, control, curve equation of suspended-cable, suspension mechanics
