    摘要:

    為提高犁體設(shè)計效率,,引入?yún)?shù)化設(shè)計和專家知識庫的技術(shù),以犁體曲面十二參數(shù)法數(shù)學模型和犁體曲面的構(gòu)成線方程為基礎(chǔ),,推導樣板曲線方程和犁托的樣板曲線方程,,通過知識庫來表達參數(shù)化設(shè)計過程中的非數(shù)值化專家經(jīng)驗和設(shè)計常識。編寫了犁體參數(shù)化設(shè)計系統(tǒng),,實例表明,,該系統(tǒng)只需輸入耕寬、耕深和耕速3個參數(shù),,可自動生成各種型號犁體及零部件的二維工程圖和三維造型圖,,設(shè)計時間由幾個月縮短為

    Abstract:

    20?min左右。To improve plow design efficiency, the parametric design and knowledge base technology were applied. Based on the plow twelve-parameter mathematical model and plow surface composition curve equation, the plow curve equation and the plow care equation were derivated. The knowledgebase was introduced into the plow parametric design to express the expert experiments and design experiments, which were necessary to the plow parametric design. A case of plow parametric design system showed that the developed software system only needs three parameters: farming width, depth and speed, the 2D and 3D engineering drawings of the plow can be created automatically, and design period is shorted from several months to about twenty minutes. 
