摘　　要：三维多向编织复合材料综合力学性能优异,有望在航空航天领域作为主承力结构而得到广泛应用。有限元分析(FEA)方法是三维多向编织复合材料宏细观力学性能研究最为经济和有效的分析手段。从细观结构模型、刚度强度性能预测及界面性能分析等方面评述了细观有限元法的研究进展;从接头结构承载性能分析和冲击性能模拟等方面介绍了宏观有限元法的研究概况;分析了目前研究中存在的主要问题并对后续的研究工作进行了展望,为研究者了解该领域的研究现状和发展趋势提供了有价值的参考。Owing to the excellent comprehensive mechanical performance, 3D multi-directional braided composites have tremendous application potentials as primary load-bearing structures in the aeronautics and astronautics fields. Finite element analysis （FEA） is the most economical and effective analysis method to study the macro-meso me- chanical properties of 3D multi-directional braided composites. The research progresses of meso finite element meth- ods, including the meso structure model, stiffness and strength property prediction and interface property analysis, were reviewed. Moreover, the research status of macro finite element method, including impact property simula- tion, load-bearing property analysis of joint structures and so on, were also introduced. The main problems existing in the present research were analyzed and the subsequent work was prospected, which provides convenient refer- ences for researchers to understand the current research situation and development trends in this field.
