【摘要】 针对将热控多层三维设计展开转换成二维CAD图纸同时展开精度小于1 mm的设计需求，提出了一套基于CATIA环境下优化的几何展开复杂曲面通用算法的方法，并开发出相应的系统。首先，利用CATIA创成式外形设计功能的提取以及填充功能，得到天线面板一片复杂曲面；然后，利用有限元分析功能的网格划分功能将曲面三角化；最后利用开发的系统，采用优化的等面积展开几何法，将复杂曲面展开，且精度满足设计需求。更多还原

【Abstract】 Aiming at the design requirements of flattening and converting the thermal control multi-layer 3D design development into 2D CAD drawings and the flatten accuracy is less than 1 mm at the same time,this paper proposes a method of geometric flatten complex surface general algorithm based on CATIA environment optimization and develops the corresponding system.Firstly,a complex curved surface of the antenna panel is obtained by using the extraction and filling functions of CATIA generative type of shape design function.Then,the curved surface is triangulated by using the meshing function of finite element analysis function.Finally,it uses the developed system and the optimized equal area expansion geometry method to flatten the complex curved surface,and the accuracy meets the design requirements.更多还原
