摘　　要：民用飞机舱门的完全互换可以有效降低生产成本和运营成本,国外先进机型已经可以实现大型舱门的完全互换,我国民机舱门制造还普遍采用修切蒙皮的方式,尚未实现完全互换。为了提高民机产品竞争力,实现舱门的完全互换势在必行。分析了民用飞机完全互换舱门设计技术难点,给出了一种完全互换舱门设计技术解决方案,包括实施过程流程图、实施方法分解说明等。详细阐述了以六自由度姿态调整为主的舱门安装调整技术,以累积容差计算为主的舱门容差管理技术,基于舱门的安装调整结果、容差管理结果、刚度匹配结果的关键零组件设计补偿技术等完全互换舱门关键技术,为民用飞机完全互换舱门设计提供了参考,可以推广应用于民用飞机半堵塞式等形式的舱门设计中。The complete interchangeability of civil aircraft cabin doors can effectively reduce production and opera-tional costs,advanced foreign aircraft have been able to achieve complete interchangeability of large cabin doors,the manufacturing of cabin doors in China still generally adopts the method of trimming the skin,and complete in-terchangeability has not yet been achieved.In order to improve the competitiveness of aviation products,it is imper-ative to realize the complete interchangeability of cabin doors.The technical difficulties in the design of completely interchangeable doors were analyzed,a solution of completely interchangeable doors were given,including an imple-mentation process flow chart and decomposition description.The key technologies of completely interchangeable door were described in detail,such as door installation and adjustment technology mainly based on six degree of freedom attitude adjustment,tolerance management technology based on cumulative tolerance calculation,key part design compensation technology based on door installation adjustment results,tolerance management results and stiffness matching results of cabin doors.These technologies provide references for the design of civil aircraft com-pletely interchangeable door.It can be promoted and applied to the design of semi plug and other forms of cabin doors in civil aircraft.
