摘　　要：为研究平流层飞艇的受力、变形及合理的结构体系布局,根据平流层飞艇结构特点,提出了十种结构体系布局方案。基于浮力与重力作用下平衡形态的原理,建立平流层飞艇结构分析方法和各体系分析模型。以一个25m验证飞艇作为对象进行了系统的数值分析,与工程弹性理论进行比较,论证了各体系的结构特点,最后提出合理的结构体系。本文对平流层飞艇结构设计具有参考价值。Ten kinds of architectures are proposed for the stratospheric airship according to the nature of structural characteristics.On the basis of equilibrium configuration of the floating airship subjected to the ascent helium buoyancy and gravity,the structural analysis procedure is developed and the analytical models are presented for the airship.Then the comprehensive numerical analysis is carried out for a 25 m long demonstration airship,the comparison of principal stress of envelope is performed between the nonlinear structural analysis and the engineering elastic theory.The structural performances are evaluated thoroughly.Finally,the reasonable architectures are proposed.Accordingly,the results herein are valuable to structural design for stratospheric airship.
