| Abstract: |
| After the analysis of Concurrent Subspace Optimization (CSSO) process,this paper points out that the function of disciplinary optimization of CSSO is to offer experiment points of response surface of system optimization.Based on this conclusion,an Updated Concurrent Subspace Optimization(UCSSO) which does not require disciplinary optimization but uses Uniform Experiment Design to arrange experiment points is presented.According to the updated algorithm,the framework of structural optimization with constraints of aerodynamics and RCS of aircraft is researched.The result of structural optimization with constraints of aerodynamics and RCS to an unmanned aircraft wing proves that UCSSO can greatly reduce calculation time and decrease the difficulty of data exchange between discipline. |
