摘要 基于复合材料渐进失效准则和刚度降阶模型,建立了复合材料燃料贮箱性能演化的表征模型和分析模型,借助有限元软件ABAQUS对内压作用下复合材料贮箱结构的渐进损伤过程进行了分析,实现了复合材料贮箱结构剩余强度的预报,通过与文献数据的比较,验证了该分析方法的有效性. The progressive failure analysis and residual life prediction of composite fuel tank are an important part of safety evaluations of RLV. In this paper, based on classical laminates theory, analytic and token models of composite fuel tank are built. By the finite element software ABAQUS, the progressive failure analysis is carried out and the residual life of a fuel tank is predicted. Compared with literature data, good agreements are obtained, which validates the methods proposed in the paper.
