| Abstract: | According to the high precision tracking requirements for the optomechatronics design project of the next generation large radio telescopes, a large Stewart platform is applied as the fine tuning of the tracking in this paper. The dynamic analysis of Stewart fine tuning platform is carried out. Based on this analysis, the kinematics accuracy analysis model is developed by using the relationship of the position vectors, and the kinematics accuracy results of the Stewart fine tuning platform are presented. These favorable results have shown the feasibility of applying Stewart platform in the next generation large radio telescopes. |
