某型机尾段结构优化设计分析

Optimal design analysis of tail boom

文章对金属材料和碳纤维复合材料成型的某型机尾段结构分别进行了研究分析,通过MSC.Pa-tran/MSC.Nastran完成了有限元模拟仿真,得到了不同构型下结构的变形、应力分布等详细情况,为尾管梁进一步减重优化设计提供参考。

This paper describes optimal design analysis of tail boom manufactured by metal and carbon fiber composite.The finite element method gives the structure simulation to get the deformation and stress distribution of tail boom by MSC.Patran/MSC.Nastran which provides reference for the subsequent optimization design and weight saving of unmanned Helicopter.
