【摘要】 本文主要研究了加筋夹芯复合壳体的结构强度。分别从对模型施加大小不等的外载,改变夹芯材料,以及改变筋的厚度及分布等三个方面,分析夹芯材料和壳体的响应,旨在了解加筋复合壳体各体素对其结构强度的影响的一般规律,为优化设计作支持。本文的研究成果可供有关工程设计参考。更多还原

【Abstract】 Strength analysis on sandwich composite material shell structure reinforced by stiffeners is performed in this paper. In order to understand the influence of the elements of sandwich composite material shell structure reinforced by stiffeners on the strength the structure responses on the core material and shell are analyzed under the applying different loads to the model, changing the core material as well as altering the stiffener’s structure by using Finite Element Method. The results obtained by authors can sustain optimization design and are very useful in engineering design.更多还原
