| Summary: | Thin-walled structures with different shapes are widely used in transportation systems as energy absorbing component to dissipate the kinetic energy during collision. In the present study, crashworthiness characteristic of thin-walled grooves aluminum tubes are studied. The aim is to protect this structure from serious damages as well as to minimize the injury to people during collision in transportation systems. Quasi-static axial crushing was performed to determine initial peak force (IPF), load-displacement curve, crush force efficiency (CFE) and specific energy absorption (SEA) of the tubes. The experimental results determine behavior of circular tubes in crushing manner, load displacement curves and initial crushing load were reduced as the slots is installed. This assists to reduce the extremely high initial peak force and improve the crushing efficiency of the structure. |
