The mesh data of these two models comes from static and modal finite element analysis respectively , and their load data possesses internal successivity . according to the correlation , finite element models support me parallel and cooperative processing of static , modal and dynamic response analysis 其中的結構瞬態(tài)響應有限元分析模型分為兩個層次的模型,其網(wǎng)格數(shù)據(jù)分別來自于靜態(tài)和模態(tài)分析有限元模型,在載荷數(shù)據(jù)上具備內(nèi)在繼承連續(xù)性。
Applying the above - mentioned method , the author developed an approximate developing - mapping system based on catia v5 using vb , realized the development computing of panel surface and auto - drawing of developed shape in catia , dealt with the problem : getting mesh data from analysis & simulation module of catia , picking up structure information data in iges , showing 2d developed model in catia 應用上述幾何展開算法,作者基于windowsnt 2000 xp系統(tǒng)和catiav5平臺用visualbasic開發(fā)了一套“不可展曲面近似展開和內(nèi)部結構信息映射系統(tǒng)”軟件,簡稱demaps系統(tǒng),實現(xiàn)了飛機壁板類零件的展開計算和展開圖形自動繪制。
In view of above problems , this article studies the key technology of mass data processing system , and design a system framework point to the triangle mesh data , which is made up of millions series of triangles . this framework resolves the problem that a computer could not read all the mass data into its storage and process them through data block partion , and also reduces the space that mass data occupies in hd by data compression 針對以上問題,本文研究了海量數(shù)據(jù)處理系統(tǒng)的關鍵技術,針對由百萬級數(shù)量的三角形構成的三角網(wǎng)格數(shù)據(jù),設計了一個系統(tǒng)框架,通過數(shù)據(jù)分塊解決計算機不能把海量數(shù)據(jù)全部讀入內(nèi)存進行處理的問題,通過數(shù)據(jù)壓縮解決海量數(shù)據(jù)占用大量硬盤空間的問題。
The construction of product data is studied in the paper . we discuss a few ways of turning the original meshed data of projects to two dimensional tables . after analyzing these , a kind of high effective and practical mode is showed , which expression is single child and single parent 文中研究了產(chǎn)品數(shù)據(jù)結構模型構造方法,詳細討論了工程數(shù)據(jù)的原始網(wǎng)狀結構向二維表的轉(zhuǎn)換的各種方式,比較分析這些方式后,作者給出了本系統(tǒng)所采用的一種高效實用的單子-單父的表達模型。
