Original abstract
This paper deals with numerical simulation possibilities of a hydroforming technology in production of a flow solar absorber with structured surface in a single technological operation. An austenitic stainless steel X5CrNi18-10 is used as a material for the production of the flow solar absorbers. In the theoretical chapters, comparison between implicit and explicit algorithms of finite element method (FEM) is performed. Experimental part of the paper includes creation of geometrical, material and computational models for the explicit and the implicit solution in software ANSYS Workbench and ANSYS LS-DYNA. Finally, due to evaluation of the experiment and FEM results, comparison between the implicit and the explicit theoretical solution of a formed part thickness is performed.
Czech abstract
Příspěvek se zabývá možnostmi numerické simulace hydroformování při výrobě průtočného solárního absorbéru se strukturovaným povrchem v jediné technologické operaci. Jako materiál pro výrobu absorbérů je použita austenitická korozivzdorná ocel X5CrNi18-10. V teoretické části je provedeno porovnání mezi implicitním a explicitním algoritmem metody konečných prvků (MKP). Experimentální část obsahuje tvorbu geometrického, materiálového a výpočetního modelu pro explicitní a implicitní řešení v programech ANSYS Workbench a ANSYS LS-DYNA. V závěru je v návaznosti na vyhodnocení experimentu a MKP provedeno srovnání výsledků simulace implicitního a explicitního výpočtu změny tloušťky lisovaného dílce.
