摘　　要：飞机检查间隔的制定需要检测可靠性提供支持,然而检测可靠性的评估受到检测过程中诸多因素的影响。其中,人员、环境这2类因素具有多维指标且水平难以量化的特点,对其开展定量建模难度较大。针对该问题,在利用HF因子对2类因素影响进行量化评估的基础上,建立了考虑人员和环境影响的检测可靠性模型。首先,对HF因子开展特征分析并结合A400M检测数据提出其数学模型,同时采用考虑工作经验和作业光照而开展的检测试验数据进行验证。其次,通过模糊综合评价进行2类因素水平的综合量化;在此基础上,建立该综合量化结果与HF因子模型之间的映射关系。最后,以平板裂纹目视检测数据为例进行了应用分析,验证了模型的适用性和有效性。所提出的检测可靠性模型有潜力在保证结果准确性的前提下降低试验成本。The establishment of aircraft inspection intervals requires the support of detection reliability,but the evaluation of detection reliability is influenced by many factors during the detection process.Among them,human and environment have the characteristics of multi-dimensional indicators and difficulty in quantifying their levels,making it difficult to quantitatively model them.Based on the quantitative evaluation for the impact of two types of factors using HF factors,a detection reliability model considering the impact of human and environment was established to address this issue.Firstly,feature analysis was conducted on the HF factors and its mathematical model was proposed based on A400M detection data.At the same time,verification was carried out using detection test data that considered work experience and operational lighting.Next,the comprehensive quantification for the levels of two types of factors was carried out through fuzzy comprehensive evaluation.On this basis,a mapping relationship between the comprehensive quantification results and the HF factor model was established.Finally,an application analysis was conducted using visual inspection data of flat plate cracks,verifying the applicability and effectiveness of the model.The proposed detection reliability model has the potential to reduce experimental costs while ensuring the accuracy of the results.
