要：利用有限元方法对运动学支撑夹紧力引起的镜片光学表面变形进行静力学分析,并应用Zernike多项式对镜片表面的变形进行了拟合。结果表明,夹紧力作用下镜片表面产生的几种主要像差为Defocus、Pri Trefoil和Pri Hexafoil。光学检测过程中,运动学支撑结构的重复装配误差可能会影响检测精度,因此分析了运动学支撑夹紧重复性对镜面面形的影响。以夹紧力大小、夹紧力径向位置、夹紧力周向位置变化引起的镜面表面峰谷（PV）值和均方根（RMS）值的变化作为评价夹紧重复性的依据。分析结果表明,镜片表面的PV值和RMS值变化不明显,说明所设计的运动学支撑结构在多次重复性的检测中允许装配过程存在一定的误差。<br /> Geometrical deformation of lens surface caused by kinematic mount clamping force is analyzed with finite element method and lens surface displacements are extracted and fitted with Zernike polynomials. Analytical results show that Defocus, Pri Trefoil and Pri Hexafoil are the main aberrations under clamping force. During the process of optical testing, repeating assembly of the kinematic mount apparatus may influence the testing accuracy, so relations between assembly repeatability and surface deformation are also investigated. In order to evaluate the repeatability for assembling, variations of peak valley （PV） and root mean square （RMS） values changed with clamping force and clamping placement in circumferential and radial direction are also shown in this paper. The results indicate that PV and RMS values do not obviously change as clamping force and clamping placement change, which means that slight assembly errors of the kinematic mount apparatus are allowed.<br /> 关键词：光学设计 镜面变形 运动学支撑 夹紧力 夹紧重复性 有限元法 Zernike多项式<br /> optical design ; deformation of lens surface ; kinematic mount ; clamping force ; assembly repeatability ; finite element method ; Zernike polynomials ;</div> <div style="height200px;"></div> </div> </div> </div> </div></div> </div> <!--autocomment filter by maxnum--> <div class="ft_wp"> <div id="ft" class=" cl"> <div id="flk" > <p> <a href="http://wpa.qq.com/msgrd?V=3&Uin=20600600&Site=光电工程师社区&Menu=yes&from=discuz" target="_blank" title="QQ"><img src="static/image/common/site_qq.jpg" alt="QQ" /></a><span class="pipe">|</span><a href="http://m.oecr.com" >手机版</a><span class="pipe">|</span><a href="http://so.oecr.com" title="站内搜索" target="_blank" >搜索</a><span class="pipe">|</span><a href="http://www.focaloptics.com" title="主办单位：武汉焦点光学技术有限公司" target="_blank" >焦点光学</a><span class="pipe">|</span><a href="http://www.oecr.com" target="_blank">光电工程师社区</a> ( <a href="http://beian.miit.gov.cn/" target="_blank">鄂ICP备17021725号-1</a> <a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821" target="_blank">鄂网安备42011102000821号</a> ) <span id="tcss"></span><script type="text/javascript" src="http://tcss.qq.com/ping.js?v=1eOg" charset="utf-8"></script><script type="text/javascript" reload="1">pgvMain({"discuzParams":{"r2":"1028778","ui":0,"rt":"plugin","pn":1,"qq":"000"},"extraParams":""});</script></p> <p class="xs0"> <span id="debuginfo"> Copyright 2015 光电工程师社区 版权所有 All Rights Reserved. </span> </p> </div> <div id="ftl" > <p>申明：本站为非盈利性公益个人网站，已关闭注册功能，本站所有内容均为网络收集整理，不代表本站立场。如您对某些内容有质疑或不快，请及时联系我们处理！ </p> </div> <div id="frt" > <div class="wp"> <p class="dd01"> © 2001-2022 <a href="http://www.oecr.com" target="_blank">光电工程师社区</a> 网站备案号：<a href="https://beian.miit.gov.cn/">鄂ICP备17021725号</a> 网站公安备案号：<a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821">鄂42011102000821号</a> Powered by <a href="http://www.discuz.net" target="_blank">Discuz!</a> <em>X3.2</em> </p><p class="dd02">GMT+8, 2025-12-17 06:48 </p> </div> </div></div> </div> </div> <!--bottombg结束--> <!--<div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> --> <div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> <script type="text/javascript">_attachEvent(window, 'scroll', function () { showTopLink(); });checkBlind();</script> <div id="discuz_tips" style="display:none;"></div> <script type="text/javascript"> var tipsinfo = '1028778|X3.2|0.6||0||0|7|1765925338|c4738cad847323ca3a58ee893a411f87|2'; </script> <script src="http://discuz.gtimg.cn/cloud/scripts/discuz_tips.js?v=1" type="text/javascript" charset="UTF-8"></script></body></html>
