Abstract The conceptual design model for mechanical product and its computer aided design are the important and focus problems. A mechanical product design process of FPBS model, function-principle-behavior-structure model, was put forward and discussed. The semantic relationships between the elements of FPBS model were studied to make foundation for the its application. The operational demands of knowledge system for FPBS model were analyzed, and it is indicated that the ontology can be applied effectively to knowledge system operation of FPBS model. Then, an ontology model was established based on FPBS and a FPBS ontology model system was further constructed. The experimental results indicate the model can be used in computer aided conceptual design for mechanical product effectively.

基于本体的FPBS设计模型研究
机械产品概念设计模型及其计算机辅助设计是目前研究的重点和热点问题.通过讨论提出了基于功能-原理-行为-结构(FPBS)模型的机械产品概念设计过程,研究了FPBS模型元素的语义关系,为模型的应用打下基础.对FPBS模型的知识系统运算需求进行了分析,表明本体能够有效地应用于FPBS模型的知识系统运算.据此提出了基于本体的FPBS模型,并进一步构建了FPBS本体模型系统.实例表明,该模型可以有效地应用于机械产品的计算机辅助概念设计.
