Abstract: (5516 Views)
One of the methods of blade production is forging. But according to the complexities of the blades, they cannot be produced in one stage and it's necessary for them to consider preform. In this research, a basic geometry with elliptical cross section for airfoil of blade, was considered and response surface method was used to optimize this preform. Optimization purposes were considered completely die filling and reduction of flash volume, forging load and strain variance. At the end, optimized preform was compared with the model of mass distribution method. Results show response surface method give better results than mass distribution method. Also physical modeling was used for verification of simulation results. Results show simulation results have a good corresponding with experimental results.
