民用飞机舱门导向槽优化设计分析

Optimal Design and Analysis of Guide Groove for Civil Aircraft Door

文章讨论民用飞机舱门结构最佳设计方案。了解设计基本要求,随之总结导向槽优化设计思路、选材与参数设定、建模环节设计的要点,最后从制造与安装、齿形公差分配、计算孔径尺寸、材料纤维方向四方面展开分析,提出导向槽优化设计建议。通过建模与拓扑优化分析,使导向槽功能、性能得到优化,同时完善了舱门结构,以期能够为今后民用飞机舱门设计积累经验。

The article discusses the optimal design scheme of the civil aircraft door structure.Understand the basic design requirements,then summarize the guide groove optimization design ideas,material selection and parameter setting,and the main points of the modeling link design,and finally analyze from the four aspects of manufacturing and installation,tooth tolerance allocation,calculation of aperture size,and material fiber direction.And then put forward the optimal design suggestion of guide groove.Through modeling and topology optimization analysis,the function and performance of the guide groove are optimized,and the cabin door structure is improved,in order to accumulate experience for the future design of civil aircraft doors.
