摘要
给出了自顶向下设计所涉及的关键技术、国内外研究现状、存在的问题及发展方向。首先介绍了自顶向下的设计过程 ;然后介绍关键技术及研究现状 ,包括产品装配模型的表达方式、装配模型的建模方法、装配模型的优化分析方法和装配顺序规划等 ;
The key technology, research state, problems and development directions of Top-down design are surveyed. First, the Top-Down design process is introduced, then, the key techndogies including the expression of assembly model, assembly modeling, the optimization and analysis method of assembly model, and assembly sequence planning are presented, finally, the development directions of those key technologies are given.
