摘要
提出了装配黑箱理念,介绍了自动装配研究的现状,并通过对零件信息模型、装配模型、装配顺序及装配位姿求解等关键问题的论述,探讨了在CAD系统中实现自动装配的机理和方法。提出了解决零件装配信息表达的“有向装配编码矩阵法”、解决位姿记录的“位姿约束向量记录法”,以及装配零件的权重值、装配母体、装配元素等新方法和新概念,为进一步研究自动装配问题提供了理论基础和方法指导。
The concept of black box in assembly was brought forward and the research on automatic assembly was introduced.The achieving mechanism and methods in CAD system were probed for by discussing of a model of component assembly information and a model of assembly line and sequence,as well as answering to the pose of assembly.The methods of code matrix of directed assembly of component information code,vector recording methods of pose restriction for pose recording,new methods and concept of priority value,as we...
