Global optimization design method study of aircraft structure

ZHAO Shaojie;Xi'an Aircraft Co.,AVIC Aircraft Co.;  
The material utilization can be improved by optimization design which makes the stress distribution and the material arrangement more reasonable. The variables,optimization regions and the response constraints are determined through decomposition of the whole aircraft structure and the optimization design method of the wing of MA700 is studied with the feasible direction method and sensitivity analysis on the MSC Nastran platform. In the analysis,the stability problem is considered and the stringer size is preliminarily determined which offers some experience for the subsequent optimization design work.
