According to the specific requirements of the sub-reflector adjustment mechanism when the 65m diameter round movable radio telescope system observes,the Stewart platform as the Shanghai 65m radio telescope antenna sub-reflector adjustment system is proposed.Based on the optimal force of the rods when the main reflector and the sub-reflector is on the whole workspace,the configuration parameters integrated design method about the consideration to the workspace and to avoid interference between the bar and other factors is researched.Configuration parameters met the real requirements are obtained.The workspace is solved under the configuration.And the feasibility of the project is verified compared to the required workspace.The research work has an important significance in the parallel mechanism for engineering practice.
