【摘要】 以某支线飞机金属机翼布置和结构模型为依据,采用CAD和CAE关联技术建立了一个复合材料翼盒有限元分析模型,考虑所有相关控制要求如应变、损伤容限、稳定性以及制造限制等,完成了结构参数优化设计。通过VB语言开发了许多辅助工具,用于大量的数据准备和结果处理。整个优化工作紧密围绕满足应变设计准则和NASTRAN优化模块进行,因此结合NASTRAN分析结果开发的后处理工具,用于结构的校核和参数改变。对优化获得的翼盒尺寸进行了独立的分析,证明了结果有效性。更多还原

【Abstract】 Base on metal wing-box model and structure of a regional jet,constructed a common composite wing-box finite element model for the static optimization and analysis purposes. Considered all relevant sizing requirements,such as structural strain,damage tolerance,buckling and manufacturing,completed composite wing box sizing optimization. Many tools were developed by VB language for preparing the required input data, as well as the analysis of the results. Since the design process is centered around the optimization procedure in Nastran and FSD criterion,Most of these tools were developed in close coordination with the MSC Software,to check and update wing structure parameter. An independent and comprehensive analysis of the conceived wing-box’s structural sizes confirmed the validity of the results.更多还原
