基于民机结构修理方案设计原则和一般方法,提出一种民机结构损伤金属补片修理方案数字化设计方法,通过研究典型金属补片修理方案的数字化设计技术,对方案设计因素和设计参数进行全面分析,得到各参数间的关联和约束关系,给出了合理的修理方案数字化实现途径。实例分析表明,该方法快捷、有效,对飞机结构修理具有工程实际意义。 Based on the design principle and general method of civil aircraft structural repair scheme, a digital design method for repair scheme of damaged metal patch for civil aircraft structure is proposed. By studying the digital design technology of typical metal patch repair scheme, the design factors and design parameters of the scheme are comprehensively studied Analysis and get the relationship between the various parameters and constraints, gives a reasonable way to achieve digital repair program. The case study shows that the method is fast and effective and has practical engineering significance for aircraft structure repair.
