| 摘 要： | 飞艇是典型的充气薄膜结构,对结构内应力、变形等的准确预测是这里结构设计的关键问题。基于有限元分析软件NASTRAN,提出了一种飞艇囊体结构仿真分析的方法。给出了飞艇模型的建立、网格的划分、约束施加和载荷处理等过程。通过对某飞艇模型在俯仰和转弯两种工况下的分析计算,得到飞艇囊体应力和应变分布,结果与实际情况符合较好。为飞艇囊体的设计提供了参考依据。

| Abstract: | The airship is typical inflatable membrane structure with large deformation and small strain. This paper introduces the airship modeling, meshing, constraints and loading process. Through the finite element analysis software NSTRAN of airship's pitching and turning two conditions were analyzed by airship, The stress and strain distribution under airship's pitching and turning two conditions are obtained with the finite element analysis software NSTRAN. The article by applying reasonable constraint and load handling gets reasonable results which is helpful for the security design of airship. |
