The primary mirror handing device with 12 axial supporting bars was designed in this paper, according to the structure and material characteristic of 4 m SiC primary mirror. Firstly, it was determined that the handing device consisted of main body frame, axial supports, radial supports and upper compaction. Secondly, with method of finite element model building, analysis and optimization, the design of main body frame, the optimization of application area of force and projected dimension were studied. Thirdly, the mirror deformation plot and stress state and the primary mirror supported by 3 points and tilted caused by the installation error were analyzed. Finally, the final project of handing device was determined, and it was machined, assembled and applied according to the results of the analysis and optimization. The analysis result and practical application indicate that the design requirement of the handing device is achieved, and the direction for similar structure is provided here.
