| Abstract: | The structural parameters have great influence on the kinematics behavior of the fine-tuning platform for the next generation la rge radio telescope. The Jacobian matrix connecting the dexterity performance of the fine tuning platform is first deduced, and then use the condition number of the Jacobian matrix as the optimization objective to proceed the structural opt imization. The optimization results are also presented, which lay a solid base f or high accuracy trajectory control of large radio telescopes. |
