In order to trace a target in deep sky, a feed cabin 20 tons in weight used for a large radiotelescope is drawn with six cables. To realize a smoth tracing all the time, optimal distribution of thecable tensions is explored. A set of cable-clog systems is utilized to control the wind-induced vibration ofthe cable-cabin structure. This is an attempt to apply the passive structural control strategy in the area ofradio astronomy. Simulations of wind-induced vibration of the structure in both time and frequencydomains offer a valuable reference for construction of the next generation large radio telescope.
