selective assembly
解釋
選擇裝配-
In the selective calculation module, the calculations of heat exchanger design, the analysis of pipe setting patterns are combined with the database so that the selective calculation sub - system is developed. considering the factors such as uniform flowing of the fluid, smaller inner radius of the shell, the well heat exchanging effect and saving materials, the pipe setting module is developed based on the designing data. in the module for automatically generating parts and assembly drawings, the database of pattern sizes and the drawing libraries are established according to the classifications and series
在選型計算模塊中，通過換熱器設計計算、管束組件的布管方式分析、數據庫的檢索，開發了浮頭式換熱器輔助設計計運算元系統；在布管定型模塊中，按照確保殼程流體流動均勻、且換熱器殼體的內徑較小、管程殼程間換熱良好且節省材料的原則，根據設計計算參數建立了自動布管定型系統；在零部件圖和裝配圖自動生成模塊中，分級分類地開發了浮頭式換熱器所有零部件圖和裝配圖的圖紙尺寸數據庫和圖庫，運用「死圖活尺寸」的開發理念，開發了圖形自動生成與管束參數化設計的集成系統。 -

摘要現有計算機輔助選擇裝配理論中只有針對單一裝配尺寸鏈的選配模型，提出基於多裝配尺寸鏈的選配模型，將計算機輔助選擇裝配轉化為多目標優化問題，新模型為各裝配尺寸鏈提供了權值和修正值。 -
The matching rate of the suggested two methods were compared for the assembly size chaims with different number of the forming links, with different number of the forming link parts, and with different deviation distribution types on the assumption that the closing link tolerance of the selective assembly is a tenth of that calcalated by the extremum method
以不同組成環數、不同組成環零件數、不同偏差分佈類型的裝配尺寸鏈為研究對象，取選擇裝配的封閉環公差為按極值法計算所得封閉環公差的十分之一，以匹配率為評價指標，比較了兩種方法的優劣。 -
Two guidelines were defined to evaluate the selective assembly quality : matching rate and assembly precision, and two computer - aided selective assembly methods were suggested : the matching according to the average deviation of the closing link and the matching according to the ideal size position of the closing link
摘要定義了評定選擇裝配質量的兩個指標：匹配率和匹配精度，提出了計算機輔助選擇裝配的兩種基本方法：按封閉環理想尺寸位置匹配和按封閉環平均偏差值匹配。 -
