Structure design optimization of the wing based on neural networks and complex method

WANG Wei1 ZHAO Mei-ying1 ZHAO Feng2 WAN Xiao-peng1(1 College of Aeronautics,Northwestern Polytechnical University,Xi’an 710072,China)(2 College of Automation,Northwestern Polytechnic University,Xi’an 710072,China)  
From the thinking of both position variables and size variables,a global method that can solve the optimization problems was present in this paper.Letting the NASTRAN optimize the size variables,using the neural network to predict the calculated result of the NASTRAN,and this paper went on to optimize the position variables with the complex method.The example shows the structural optimization method that use Neural Networks to predict the result of the NASTRAN has high precision and adaptability.this method is not only correct and feasible,but highly effective and practically convenient.
