摘要
通过分析影响产品维修性的各种因素,确定了产品维修性设计属性;以维修作业虚拟仿真、上肢评价技术、维修性核对表等方法为基础,给出了维修性各属性值的确定方法。利用多属性决策理论,提出了维修性属性值的规范化方法,构建了基于多属性决策方法与模糊理论的产品维修性的评价模型。最后,结合两种不同类型的民用飞机前起落架系统的虚拟样机给出了分析实例,证明了方法的有效性。
Maintainability design attributes of product are determined by analysis of maintainability influencing factors; and the calculation method of each attribute was proposed by means of maintenance task virtual simulation, rapid upper limb assessment and maintainability checklist. In terms of multiple attribute decision--making theory, the normalization methods of maintainability attributes were proposed, and the comprehensive maintainability evaluation model of products was established based on fuzzy theory and multiple attribute decision making method. At last, a comprehensive evaluation instance, combined with two different types of nose landing gear system＇s virtual mock--ups,was given to illustrate the effectiveness of the model.
