摘要	In order to solve the problems of large calculation data volume and failure caused by the post processing mode of interface program in the process of optical machine system dynamics analysis and surface shape optimization, the pre-processor was introduced into the opto-mechanical interface processing for integrated analysis and optimization of opto-mechanical system. First, the node area weighting factor and annular Zernike polynomial were introduced to settle non-orthogonality of standard Zernike polynomial within annular discrete field. And a calculation method was proposed to solve node area weighting factor by imposing uniform pressure on mirror surface to solve the bearing reaction force of the node. Then, the least square method was used to deduce the linear relation expression between rigid body deformation of mirror surface, Zernike polynomial coefficients of fitting mirror deformation and deformation of each note on mirror surface. Finally, the interface program was wrote and these linear expressions were channeled to finite element model by the way of Multiple Point Constraint (MPC); what's more, the systematic interface pre processing of the optical machine was completed. Through making structural dynamics random response analysis on vibration of the bore-sight on 1.2m certain ground-based telescope caused by unsteady state wind load and high-order deformation of the main mirror surface supported by hydraulic whiffletree, the effectiveness of optical machine preprocessing method to the problem of optical machine system dynamics was verified; through taking the shape of the mirror as the optimization objective, the sensitivity analysis was made on the structure size of 1.2m lightweight lens body of primary mirror to verify the optimization analysis process of the mirror shape which was subject to be effectively simplified by the optical preprocessing method. 2017, Science Press.
