| Abstract: | Static analysis and modal analysis on the structure of telescope main rotary frame was achieved by means of finite element method. A simplification of model has been carried out by the use of methods of establishing rigidity zone and coordinates transformation. The establishment of structural model based on finite element analysis and its process of simplificatioda treatment were expounded. The static and modality analytical computation have been achieved by the use of ANSYS software. By means of the result of analysis, references and suggestions were provided for engineering practice and a kind of new train of thought was provided for the analysis of main rotary frame. |
| Keywords: | finite element telescope main rotary frame static analysis of structure modality analysis |
