Manufacturing of a Component by Using Hydroforming Technology and Its Optimization
 Harant, Martin ; Peterková, Eva (oponent) ; Řiháček, Jan (vedoucí práce)
The project deals with analysis and optimization of the geometry of the stamped part produced by the pillow hydroforming. The blank consists of two sheets of steel DC01, which is welded by laser beam. The forming process can cause excessive thinning and cracking of the part. By evaluation of mechanical tests is created material model, which is the basis for numerical simulation created in software PAM-STAMP. The outputs are analysis which provide information about critical points, failure pressure, limiting deformations and prediction of springback. Validity of the numerical simulation is verified by comparison with the experimentally obtained data. The comparative criterions are the failure pressure and the material thickness at various locations. Based on the results of the numerical simulation, the optimization of the geometry is created. The optimization uses different values of radius at the crack point.
