Study of Energy Absorption of Rectangular Tube of Bumper of Light Commercial Vehicle during Oblique Loading

S. B. Tuljapure , Dr. S. S. Sarawade

Thin walled structures are used as energy absorbers for last few decades. The absorption of energy takes place during progressive folding process of the tube. Tubes with different shapes are studied by many researchers. In this research work, a rectangular steel tube of bumper of light commercial vehicle is subjected to axial & oblique impacts. The mean crushing load determined by using equations of square tube are used to validate the results of finite element analysis. The reduction in energy absorption during the oblique impacts is studied. Effect of oblique loading on mean crushing load, peak load & crush force efficiency are observed during this work.
