摘要

Diplomová práce se zabývá výpočtovým modelováním deformaeni-napi»ových stavu přední deformační zóny závodního auta při podmínkách rázového zatížení užitím metody konečných prvků. Tento typ úlohy se řadí mezi rychlé dynamické dije, a proto byl použit řešič s explicitní formulací metody konečných prvků. Pro výpočet byl použit program LS-DYNA. Cílem práce je posouzení vlivu této deformační struktury na změnu kinetické energie vozu a množství pohlcené energie při čelním nárazu.
