摘要
从复合材料的基本力学特征和多墙结构承载的基本力学原理出发,结合工程实践的具体需求,对该结构建立承载能力计算模型,推导计算承载能力的公式,特别是多墙结构后屈曲承载能力的分析,并编写了一套分析软件。通过实例计算,并与实验结果进行对比,发现该软件具有计算精度高、计算时间短的优点。可解决飞机设计面临的复合材料多墙结构的承载能力的计算问题。
A model is established based on the basic mechanics characters of composite materials and the basic mechanics theory of the multi- spar structures, combining the request from engineering practices. The equations of loading capability are deduced, especially in post-buckling of the multi-spar structures, and the analyzing software is designed. The validity and effectiveness of the software are demonstrated by comparing the application with experiment. The software with high accuracy and short-time-consumption can solve the analytical problem of composite multi-spar load capability faced in the aircraft design.
