Journal Name:

Publication Year:

Abstract (2. Language): 
S-shaped structure with square section considered as low fence of car chassis. There are geometrical variables for this structure such as length as width of thin-walled structure, radius and arc angle of S-shaped axis, width and thickness of square section. In addition, variables related to CFRP such as number and angle of fibers can be having significant effect on performance of CFRP absorber energy. The principle aim of this paper is parametric study on CFRP S-shaped energy absorber. 30 various FEM model of structure is created with various values in four input variables and then amount of energy absorption and amount of peak crushing force calculated for any models and in the end, a table is presented according to four inputs and three outputs.
