| Abstract: | A new test platform consisted of two layers of Stewart platform was presented in this paper. The platform was developed for the pre research of feed fine tuning of large radio telescope. The main advantages of this test platform, compared with a typical Stewart platform, are the capabilities of real time measuring, tracing and locating. In this paper the design of the mechanism was introduced in detail firstly. Then the forward and inverse kinematics problems of the test platform were analyzed. Furthermore, the required workspace of the test platform was testified to be assured according to geometric constraints. The computer simulation result of the workspace was also obtained, and it will be used in the optimal design of large radio telescope in the future. |
