    摘要:

    為提高犁體設(shè)計(jì)效率,引入?yún)?shù)化設(shè)計(jì)和專家知識(shí)庫(kù)的技術(shù),以犁體曲面十二參數(shù)法數(shù)學(xué)模型和犁體曲面的構(gòu)成線方程為基礎(chǔ),推導(dǎo)樣板曲線方程和犁托的樣板曲線方程,通過知識(shí)庫(kù)來表達(dá)參數(shù)化設(shè)計(jì)過程中的非數(shù)值化專家經(jīng)驗(yàn)和設(shè)計(jì)常識(shí)。編寫了犁體參數(shù)化設(shè)計(jì)系統(tǒng),實(shí)例表明,該系統(tǒng)只需輸入耕寬、耕深和耕速3個(gè)參數(shù),可自動(dòng)生成各種型號(hào)犁體及零部件的二維工程圖和三維造型圖,設(shè)計(jì)時(shí)間由幾個(gè)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. 
