高功率激光设备中大型光学元件的精确装配设计和性能优化是一个长期存在的技术挑战，包括许多复杂问题的组合，涉及机械，材料和激光束物理。方法提出了一种基于多物理场分析和数字仿真的增强虚拟装配框架，用于大型光学器件的装配优化。该框架侧重于产品的结构和装配参数对其光学性能的基本影响；三维仿真技术提高了冲击的精度和可测量性。大型光学元件的装配方案受动载荷和非线性环境激励等一系列约束条件的影响较大，为此提出了一种智能迭代计算算法。结果最后，以孔径为410 mm的变频器为例，进行了详细的说明和讨论，以验证所提出系统在大型光学装配和安装工程中的性能。
BackgroundA 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.MethodIn 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.ResultsFinally, 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.
