浅谈光学镜片亚表面损伤形成数值模拟与分析

摘要

在光学镜片的研磨加工过程中，所产生的错位、微断裂等亚表面损伤，会削弱光学镜片的强度，影响其长期稳定性，从而降低光学镜片的最终质量。因此为提高光学镜片加工质量与效率，满足日益增长的光学镜片市场需求；在抛光过程中，必须寻求有效方法，去除加工中产生的亚表面损伤。在现阶段的光学镜片亚损伤仿真研究中，仿真建模作为其研究过程中的重要组成部分，对于亚表面损伤的形成能够进行更加细致的模拟分析，从而最大程度上减少仿真结果与实际工程的误差，有助于将实验与理论相结合，指导光学镜片的研磨加工。本文就光学镜片亚表面损伤的形成进行数值模拟与分析探究，为相关技术研究提供参考。

Abstract

In the grinding process of the optical lens, the subsurface damage such as dislocation and microfracture will weaken the strength of the optical lens, affect its long-term stability, and thus reduce the final quality of the optical lens. Therefore, in order to improve the processing quality and efficiency of optical lenses and meet the growing market demand of optical lenses, effective methods must be sought to remove the subsurface damage. In the present stage of the optical lens subdamage simulation research, simulation modeling as an important part of the research process, for the formation of subsurface damage can be more detailed simulation analysis, to minimize the simulation results and actual engineering error, help to combine experiment and theory, guide the grinding of optical lens processing. This paper conducts numerical simulation and analysis of subsurface damage of optical lens to provide reference for related techniques.
