| 摘 要： | 介绍了光机热集成分析技术的基本原理及其关键技术———数据传输技术的研究现状和最新进展。通过接口工具Zernike多项式进行数据传输的基本过程是:数据处理,即将有限元分析中得到的变形结果转换成基于弧矢坐标系或基于波前坐标系的数据形式;多项式拟合,即利用最小二乘法或Gram_Schmidt正交化方法进行拟合。提出了自动数据转换接口程序,它能够简化光机热集成分析的过程,可提高工作效率。

| Abstract: | Some current states and new advances in the research of the basic theory of thermal-structural-optical(TSO)integrated analysis,and the interface problem of data transmission in mechanical,thermal and optical program are reviewed.It is demonstrated that Zernike polynomial as data transmission tool fitted process: the data manipulation——the displacement data provided by FEA tools must be translated into either a sag-based or wavefront-based coordinate systems. The polynomial fitting——methods of wavefront fitting using Zernike polynomial are described: least square method and Gram-Schmidt orthogonalization method. On these foundations the data transmission interface program can make the TSO process simple and can increase efficiency. |
