%X 针对机身大开口结构的受力特点，采用工程方法分别研究了开口区结构在垂向载荷、侧向载荷及扭转载荷下的应力分布规律。通过对开口区的应力分析并与对应封闭机身圆筒结构的最大应力和剪流的对比，总结了边梁相对面积以及开口角度对开口区结构强度的影响规律。通过理论计算与试验数据的对比，对所采用的工程设计分析方法进行了验证，表明本文所用的工程方法可用于大型运输机开口结构的强度设计。<br>The work is focused on engineering design to determine the strength of fuselage structure with large opening under vertical load, lateral load and torsional load. The fuselage stress between the closed fuselage section and the fuselage section with large opening is calculated and compared. The influence of the side beam area ratio and the size of opening on the strength of opening sections are investigated. The present engineering method is validated by comparing with the testing results. It is illustrated that the present method is applicable in the large scale aero-transport fuselage design with large opening
