Parametric study of an automotive crash absorber: From analytical to FE analysis
Abstract eng: The use of a crash absorber in a vehicle is to absorb energy. The homologation procedure of vehicles makes use of many crash tests, which are extremely expensive for car manufacturers. This discussion aims to define a methodology for crash absorber design in automotive applications. The objective is to understand the effect of geometrical parameters starting from the theory of circular and square sections. A new approach for square and rectangular sections is then created. It has therefore been possible to define a preliminary concept characterized by the main geometrical parameters such as thickness, length of the two sides and fillet radius of the section and axial length. A finite element analysis was then performed to validate this. Furthermore, a DoE analysis (Design of Experiments) was performed, explaining the influence of complex geometrical parameters such as inner plate reinforcement and indentations in order to trigger the folding mechanism.
