Abstract

The bachelor thesis deals with the design of the rear underrun barrier according to the valid legislation of the Economic Commission for Europe of the United Nations - Regulation No. 58 and its subsequent strength calculation. In the opening part, its function is described and a research of existing types and designs of rear underrun barriers is discussed. In the following second part, three concepts of the barrier are presented and their individual design solutions are described in agreement with UN/ECE Regulation No. 58. In the next section, all three designs are submitted to preliminary check numerical calculations using the finite element method. Finally, their comparison is made together with a mass reduction of the most suitable rear underrun barrier evaluated.
