摘　　要：短边距是民用飞机制造过程中出现的一种典型的装配偏离。该文以某型号民用飞机垂直安定面肋和蒙皮装配过程中出现的短边距偏离为例,对其结构形式进行了分析,并从静强度、疲劳强度和损伤容限3个方面对其进行了强度分析,并根据强度分析结果判断其对客户影响。该案例完整描述了短边距偏离的工程分析过程,能够协助工程人员快速、准确的处理该类问题,并满足民用飞机的安全性和适航性要求。Short edge distance is a typical assembly rejection during civil aviation production.In this thesis we take a short edge distance of a rib and skin in vertical stabilizer for example and evaluate the structure,static strength,fatigue strength,damage tolerance and customer influence of this example.The engineering evaluating of this short edge distance can assist engineers to solve the rejections rapidly and accurately and make sure the airworthiness.

关 键 词：短边距 损伤容限 客户影响
