【Abstract】 A Stewart platform is assembled in the suspended feed cabin of the large radio telescope as a precise adjusting system for the position and orientation of the feed. The formulae are deduced to calculate the resultant actions of the Stewart platform to the feed cabin. Furthermore the ef fects of the orientation of the cabin, the adjusting velocity and the mass of th e Stewart platform to the resultant actions are analyzed. The research serves as a foundation for designing the mass ratio between the feed cabin and the Stewa rt platform to eliminate the dynamic effect of the Stewart platform on the feed cabin.更多还原
