摘　　要：半堵塞式舱门有着不传递机身载荷、初始运动向内、向外打开不占用机内空间等优点,所以半堵塞式舱门在民用飞机上的应用得以普及。半堵塞式舱门主结构的强度分析对于确保舱门的功能性和结构安全性具有重要的意义。以某机型舱门为例,进行半堵塞式舱门细节有限元模型的分析和研究。通过将有限元计算结果与试验结果进行对比分析,表明所采用的舱门有限元模型的简化原则是合理、有效的,为同类型舱门的强度分析提供参考和借鉴。With the advantages of not transferring fuselage load,inverted initial movement and not taking cabin space at open position,semi-plug doors are widely applied in civil aircraft. It is important to analyze the structural strength of the main structure of the semi-plug doors to ensure the function and security. The detailed finite element method is adapted to analyze a certain semi-plug door. The comparison of the calculated results and the test results shows that the simplified principle of finite element is reasonable and effective and it can provide reference for strength analysis of the similar doors.
