摘　　要：以平纹编织面板蜂窝夹芯结构作为研究对象,通过建立渐进损伤失效分析模型,研究参数的随机性对结构侧压强度的影响。首先通过有限元分析得到随机输入样本对应的输出响应,基于Kriging方法建立代理模型,采用基于蒙特卡洛的可靠性分析法进行结构可靠性分析,利用基于方差和基于失效概率的灵敏度分析法进行结构灵敏度分析,计算得到结构的可靠度指标与结构各力学性能参数和厚度的灵敏度指标,为结构的可靠性优化设计提供依据。For plain woven faceplate honeycomb sandwich structure, the progressive damage failure analysis model is established to study the influence of the randomness of parameters on the lateral compressive strength. Firstly, the output responses corresponding to random input samples are obtained by the use of finite element analysis, and the surrogate model is established by Kriging method. The reliability analysis method based on Monte Carlo is applied for structural reliability analysis, and the sensitivity analysis methods based on variance and failure probability is respectively used for structural sensitivity analysis. The structural reliability index, the sensitivity index of the mechanical properties and thickness are computed, which provides a basis for the structural reliability optimization design.
