Certification requirements and static design loads of Auxiliary Power Unit ( APU) mounting system in commercial aircrafts are introduced. An APU mounting system is taken as an example to explain static strength analysis and certification tests methods. Comparison of test stress values of mounting rods with theoretical computation values shows that the theoretical analysis method of APU mounting system is conservative and the design meets the certification and static strength requirements.%介绍了民用飞机辅助动力装置安装系统静强度设计的适航标准要求和设计载荷.以某型飞机辅助动力装置安装系统静强度设计为例,介绍了辅助动力装置安装系统的静强度分析和试验验证方法.安装拉杆的试验应力值和理论应力值的对比分析表明对安装系统的理论分析方法保守,其设计满足静强度要求和适航条款要求.
