  • To achieve the positioning optical components of a reference sphere in a interferometer accurately, a flexure barrel was designed. The mechanical model, structure parameter, positioning accuracy and lens deformation of the structure was studied. Firstly, a spring model system was established based on the principle of material mechanics. According to the mechanical equation and geometry relations, a binary equation of the center position of lens and the flexure's deformation was given. Then, the effects of assemble position, temperature, and structure parameters on the the positions and force of the lens were analyzed. Finally, the mechanical performance of the designed structure was analyzed by using the FEA method. The results indicate that the results of numerical simulation is coincident with that of finite element simulation well, and the best thickness of the flexure barrel is 1.5 mm, which fully meet the requirements of the reference sphere in the interferometer for the positioning accuracy and stability of the lens barrel.
