Virtual assembly framework for performance analysis of large optics

Background A longstanding technological challenge exists regarding the precise assembly design and performance optimization of large optics in high power laser facilities,comprising a combination of many complex problems involving mechanical,material,and laser beam physics.Method In this study,an augmented virtual assembly framework based on a multiphysics analysis and digital simulation is presented for the assembly optimization of large optics.This framework focuses on the fundamental impact of the structural and assembly parameters of a product on its optical performance;three-dimensional simulation technologies improve the accuracy and measurability of the impact.Intelligent iterative computation algorithms have been developed to optimize the assembly plan of large optics,which are significantly affected by a series of constraints including dynamic loads and nonlinear ambient excitations.Results Finally,using a 410-mm-aperture frequency converter as the study case,we present a detailed illustration and discussion to validate the performance of the proposed system in large optics assembly and installation engineering.
