复合材料结构可靠性分析和设计国內外均处于起步阶段。本文根据纤维复合材料的特点提出了一种复合材料迭层结构系统可靠性分析的新方法——复合材料迭层板可靠性分析的全量载荷法。文中以某一π/4均衡对称迭层板为例,计算了在承受轴向拉伸载荷、剪切载荷及拉剪联合载荷作用下的可靠度、给出了如何运用全量载荷法计算复合材料迭层结构可靠度的具体方法。文中在阐明复合材料迭层结构可靠性分析的特点及可靠度计算的基础上还从可靠性设计的观点作了分析。
The reliability analysis and design of composite structures are at the initial stage both at home and abroad. Based on the characteristics of fiber composites, this paper presents a new method for the reliability analysis of laminated structures of composites - the full load method for the reliability analysis of laminated materials. Taking a certain π / 4 balanced symmetrical laminated plate as an example, the reliability of the composite under axial tensile load, shear load and combined tension and shear loading is calculated. The method to calculate the composite material The specific method of the reliability of the laminated structure. In this paper, the reliability analysis of the laminated structure of the composite material is clarified, and the reliability design is also analyzed.
