    摘要:

    為提高模面型面設(shè)計的效率與穩(wěn)定性,提出了一種基于截面線模板的參數(shù)化優(yōu)化方法。首先對2-D截面線的特征和類型進(jìn)行分析,給出截面線統(tǒng)一的NURBS顯式表達(dá)式;然后針對截面線的結(jié)構(gòu)特點,提出一種簡捷、高效的截面線編輯策略,并設(shè)計相應(yīng)的優(yōu)化算法。將算法集成到自主開發(fā)的沖壓成形分析軟件DCiP模面設(shè)計模塊,并與HyperForm的Die Module進(jìn)行比較,結(jié)果表明:算法避免了現(xiàn)有方法中飛逸、越界等異常的發(fā)生,簡化了用戶的操作,縮短了產(chǎn)品的設(shè)計周期。

    Abstract:

    To enhance the efficiency and stability of dieface design, a parametric optimization method based on the template of section feature was proposed. The 2-D section feature was generally represented in NURBS form while its characteristics were systematically analyzed. Then, an optimization algorithm was designed with a simple and effective editing strategy. With the algorithm integrated into the independently developed DCiP forming analysis system, a comparison with HyperForm Die Module was made. The results showed that the proposed method could avoid abnormal problems, and had great ability to simplify user operations and shorten product design periods. 
