汽车覆盖件相似实例检索方法研究

CBR技术越来越多地应用于冲压件的智能冲压工艺设计、模具设计中,并将冲压件信息作为实例模型的问题域,将冲压工艺/模具信息作为解答域.冲压件的相似性计算与检索对实现冲压工艺或模具的CBR设计至关重要,因为制件是冲压工艺设计或模具设计的依据.以复杂冲压件--汽车覆盖件为对象,研究了覆盖件的相似度计算与检索问题,提出了一种基于覆盖件编码的相似制件检索方法.考虑覆盖件的特征及特征间的关系,设计了编码结构,并针对索引编码设计了相应的实例相似度计算方法.最后用算例说明了实例检索方法的有效性.

Research on Automobile Panel Case Retrieval Methodology

CBR(Case-based reasoning)technology is increasingly applied in the process planning and die intelligent design for stamping parts.In these applications,stamping parts information is acted as the problem domain of cases model,while stamping process and die information as the answer domain.The similarity computation and retrieval of stamping parts cases is essential to the case-based design of stamping process planning and die.That issue is studied targeting automotive panel as the most common complex stampin...
