- Abstract
- In this research, the effect of the thickness on the collapse characteristics of energy absorbers with compound cross sections (including rectangular and elliptical cross sections) was investigated and optimized using experimental and numerical tests. The samples were simulated using LS-DYNA software. Two types of ABS and PLA filaments were used and a total of 36 different modes were simulated. The basic structure of all the simulated samples consisted of two semi-elliptical enclosed in a complete rectangle. In order to extract optimal samples, first the results obtained in numerical simulations were used and quadratic polynomial functions were extracted for parameters of specific energy, maximum force and crush force efficiency. These functions were extracted using response surface method (RSM) and Minitab software. The obtained results showed that among the absorbers made with PLA, the samples with the thickness of the rectangular part equal to 1 mm and the thickness of the elliptical part equal to 3 mm had the most optimal conditions. Also, the results obtained using optimization showed that in the structures made with ABS filament, the most optimal conditions were for ABS1-31 and ABS2-13 samples.
