Nowadays biomimetics is widely used in the design of thin-walled structures due to the effectiveness of natural patterns to absorb energy during collisions of transport systems. With this in mind, and considering the excellent cushioning properties of the luffa sponge, the current article purposes the design and evaluation of luffa-inspired bionic thin-walled structures (BTWS). For this purpose, four BTWS were designed and numerically evaluated by a quasi static compression tests. In general terms, the bioinspired cross-sections are formed by a main circular shape, with smaller semicircular patterns along the perimeter. The accuracy of the results was ensured through the experimental validation of an initial discrete model. According to the numerical results, all the BTWS exhibited an improved energy absorption performance in a range from 19% to 38% respect to a conventional circular profile. Comparing only the BTWS, the structure BL-04 showed the best CFE performance of 0.613. Finally, a crashworthiness application for this profile as crash box for automobiles is presented.

摘要

Nowadays biomimetics is widely used in the design of thin-walled structures due to the effectiveness of natural patterns to absorb energy during collisions of transport systems. With this in mind, and considering the excellent cushioning properties of the luffa sponge, the current article purposes the design and evaluation of luffa-inspired bionic thin-walled structures (BTWS). For this purpose, four BTWS were designed and numerically evaluated by a quasi static compression tests. In general terms, the bioinspired cross-sections are formed by a main circular shape, with smaller semicircular patterns along the perimeter. The accuracy of the results was ensured through the experimental validation of an initial discrete model. According to the numerical results, all the BTWS exhibited an improved energy absorption performance in a range from 19% to 38% respect to a conventional circular profile. Comparing only the BTWS, the structure BL-04 showed the best CFE performance of 0.613. Finally, a crashworthiness application for this profile as crash box for automobiles is presented.
