Abstract

In order to quickly obtain the optimal bonding styles in the adhesive bonded mirror, the simulation and experimental study of the adhesive bonding assembly process for plane mirror were carried out. A single-factor experiment was designed to study the variation of the PV and RMS values of the surface-shape of optical plane mirror with the change of various factors. Then, an orthogonal experiment was designed to study the optimal parameters for the optimal bonding process by taking the PV and RMS of the surface-shape as comprehensive indexes. A finite element model named "Mirror-Adhesive -Frame" was developed using ANSYS Parametric Design Language (APDL) to calculate the PV and RMS values of the surface-shape of the mirror after bonding. In addition, a interference instrument named ZYGO is used to verify the correctness of the surface shape from simulation. The results show that the prediction results of the developed simulation model are in good agreement with the measurement results. The values of surface shape index PV and RMS increase with the increase of adhesive layer diameter and thickness, and gradually decrease with the increase of adhesive layer position in R direction and H direction. The orthogonal experiment with four factors and three levels revealed that the diameter of adhesive layer is the main factor to change the shape of the surface. The optimal process parameters are as follows: adhesive layer diameter of Φ4mm, adhesive layer thickness of 0.1 mm. adhesive layer position in R-direction of 40 mm and adhesive layer position in H-direction of 9.5mm.
