Description

<p>EVs are about 30% heavier on average than similar-sized engine vehicles due to the weight of their batteries. Therefore, it is crucial to reduce the weight of the components. In this paper, we focused on the impact energy absorption member, and the possibility to use the cylindrical honeycomb structure as an impact energy absorption member was investigated. First, an impact analysis of the cylindrical honeycomb was performed to compare the impact energy absorption performance with the box beam and the conventional tubular honeycomb structure. As a result, it was shown that the cylindrical honeycomb has a high impact on energy absorption performance. Next, the coating method of the cylindrical honeycomb core was investigated. It was shown that spray painting, which influences less environmental load, could be available to paint the cylindrical honeycomb core with complex geometry.</p>
