Study on optimization of stir head for FSW based on genetic algorithm

Abstract

The shape selection of stir head is processed to Friction Stir Welding (FSW), and the mathematical model and constraints for the optimization of stir head are established, what is more, the multi-target optimization algorithm of stir head dimension based on genetic algorithm is presented. Utilizing this algorithm, an example of optimization is analyzed, and its optimized finite element modeling is given, at last the reasonable dimension parameters are obtained. © 2006 International Federation for Information Processing.
