摘要
讨论了目前进行车身结构概念设计的缺点,设计了基于NX的智能化车身结构概念设计的工具———IVCD。IVCD基于车身模板技术,可快速生成车身概念结构几何模型和有限元模型;它还基于参数数据库集成了车身设计、分析和优化,实现了参数共享和更新,并采用知识向导界面,易学易用。本文给出了IVCD的系统结构和实现过程,最后通过一个IVCD计算实例证明了该工具的可靠性和有效性。
After the discussion of the shortcomings of traditional vehicle structure concept design methods, an intelligent tool named IVCD based on NX was implemented. Template method was used in IVCD system to quickly and easily build vehicle body concept geometry model and FEM model. This IVCD can integrate body design, analysis and optimization on one CAD platform through parametric variable database and all parametric variables were shared and updated in different phase of IVCD. A knowledge based wizard UI was used to make user manipulation easier. The procedure of implementation and IVCD system function diagram were provided and an example shows the reliability and validity of this tool.
