Abstract

In our everyday lives, we spend more and more time in our vehicles, where we are exposed to growing accident hazards. That is why we are increasingly focusing on security. This is particularly true for electric cars, where the size of the power source and the firewall are not the same as for conventional vehicles. The so-called energy-absorbing zone has a key role during an accident. In the era of modern materials the aluminum foam can works as an energy-absorbing structure. However, the machining of this material is hard at this time. This article attempts to investigate, through Computed Tomography-CT technology, whether the material has a permanent deformation or dimensional variation in the structure of the material can be achieved by the ultrasonic milling process.
