摘要
材料选择直接影响产品性能,是机械产品设计制造的重要一环。材料选择需要考虑材料全生命周期,涉及多领域专业经验知识,需要一个开放知识驱动的工程材料选择方法。本次研究提出一个基于本体的工程材料选择知识概念模型和开放的知识表示框架,基于该本体模型可以为新的产品设计材料选择提供语义检索;将产品设计需求与制造、使用和材料特性等之间的映射关系通过知识规则进行开放的显式定义,通过知识推理自动获取材料选择特性指标,有助于高效和高质量完成材料选择。最后以压铸模具材料选择为例,展示了基于知识推理的材料选择过程。所提出的材料选择知识表示方法具有较好的开放性和知识表达能力,为开放知识驱动的工程问题智能解决方案提供有益的尝试。
Material selection is an important part of mechanical product design and manufacturing,and directly affects product performance.Material selection needs to consider the entire life cycle of materials,involving multi-domain professional experience and knowledge,and requires an open knowledge-driven engineering material selection method.This research proposes an ontologybased conceptual model of engineering material selection knowledge and an open knowledge representation framework.Based on the ontology model,semantic retrieval can be provided for new product design material selection.The mapping relationship between them is openly and explicitly defined through knowledge rules,and the characteristic indicators of material selection are automatically obtained through knowledge reasoning,which is helpful for efficient and high-quality material selection.Therefore,taking die casting mold material selection as an example,the material selection process based on knowledge reasoning is shown.The proposed material selection knowledge representation method has good openness and knowledge expression ability,and provides a beneficial attempt for intelligent solutions to engineering problems driven by open knowledge.
