Energy absorption of impact damper
The front and rear of the vehicle should be protected in such a manner that low speed collisions will only damage the vehicle slightly, or not at all. Kinetic energy due to the low speed collision could be as high as 1000 J. If this impact energy is not dissipated properly, it could damage the bumpe...

In this project, circular tube was investigated to absorb the impact energy during low speed collision at 4 km/h. The thickness and length that gives hoop stress lower than yield strength of the material is selected. .
