| Popis: | Triggers can be implemented in the design of crash box to help in achieving desired deformation pattern, energy absorption and peak force value. In this study, crashworthiness of glass fibre reinforced plastic (GFRP) composite crash box structures with novel geometrically intrinsic triggers has been studied extensively for different types of geometric cross sections. In this study, GFRP crash boxes with four types of cross sections: square, cylindrical, hexagonal and decagonal are considered. Six different types of novel triggers, namely; type-1 slot, type-2 slot, type-3 slot, thickness variation 1, thickness variation 2 and thickness variation 3 are applied to all the types of crash boxes. A comparative numerical analysis is done to study the effect of each trigger on the energy absorption of crash boxes in low velocity impact, based on the ‘Research Council for Automobile Repairs’ test popularly known as the ‘RCAR’ test. Force versus displacement curves were plotted for each case providing detai... |
