Direct electric resistance heating allows fast and uniform of rectangular blanks in hot forming process. To adapt this technology for any blank shape, a solution is proposed by splitting the part several strips heated generators. By optimizing number, orientation dimensions to reduce added material energy costs, method applied case windscreen upright blank. From 3D thermoelectric model taking i...

Deep drawing is characterized by extremely complex deformation that influenced process characteristics such as die and punch shapes, blank shape, holding force, material properties, lubrication. The optimization of the deep a challenging issue due to complicated functions define relate parameters. However, essential enhance productivity product cost in process. In this paper, MATLAB toolbox (Pa...

A practical three-dimensional shape optimization for aerodynamic design of a transonic wing has been performed using Evolutionary Algorithms (EAs). Because EAs coupled with aerodynamic function evaluations require enormous computational time, Numerical Wind Tunnel (NWT) located at National Aerospace Laboratory in Japan has been utilized based on the simple master-slave concept. Parallel process...
