组合曲面的空间环切等距加工 - The effect of load on the crack is discussed using numerical simulation approach . then , the data mining approach to the unfavorable load combination of the crack is proposed using artificial neural network . the rule of the unfavorable load combination of the crack is generated and three dimensional load combination is given
( 2 )概要阐述了温度场的仿真，研究了薄层单元和分布裂缝模型，应用数值仿真分析方法，结合工程实际，分析了荷载对裂缝的作用效应；在对人工神经网络方法与数据挖掘关系深入研究的基础上，提出了基于神经网络的裂缝不利荷载组合挖掘方法，提取裂缝的不利荷载组合，并研制了三维荷载组合曲面图。 - 2 ) for making the meshes consistent on the common boundaries of adjoining surfaces , a new approach of boundary discretization is employed . 3 ) the boundary - representation structure is adopted to fulfill the mesh generation over combined surfaces . 4 ) the quality of surface meshes is improved by point creation on 3d scan lines and diagonal swapping procedure
通过引入可移动的虚边界解决了闭合曲面的剖分问题；通过对邻接曲面公共边界的统一处理，保证了组合曲面拼合处网格的相容性；以边界表示数据结构为基础实现了三维组合曲面的全自动网格剖分；采用空间扫描线布点、诊断交换等技术，优化了网格的质量；并以autocad为支撑平台objectarx为开发工具，开发了一个基于几何造型的曲面三角形网格全自动生成程序。 - This static finite element modeling method does n ' t need the requirement of the dynamic design of product in the modern industry . otherwise , most work on the surface mesh generation is based on the single trimmed surfaces , and the work to closed surface and combined surface , which are very popular in engineer , is very few
另外，在曲面网格划分方面，当前的研究大多是针对单张非闭合曲面进行的，对于闭合曲面和组合曲面的研究甚少，而这些曲面在实际工程中却是经常使用的。
