MSC Nastran优化功能在结构强度设计中的应用

Application of MSC Nastran Optimization Function in Structural Strength Design

对某型飞机机翼主梁,以MSCPatran、MSCNastran为基本工具,对其结构进行优化设计.优化后的结构重量、梁缘条面积、梁腹板厚度满足工程实际要求;通过有限元分析,翼尖扰度也满足变形要求.

The finite element model of wing girder is built with MSC Patran, and by using MSC Nastran the optimization is designed. The structural weight, area of girder edge and thickness of web are satisfied with the need of engineering. The wingtip deformation is also satisfied with the distortion.
