Abstract
Thin-walled structures have been widely used in automobile body design because of its good lightweight and superior mechanical properties. For the energy-absorbing box of the automobile, it is necessary to consider its working conditions under the axial and oblique impact. In this paper, a novel hierarchical honeycomb is proposed and used as filler for thin-walled structures. Meanwhile, the crashworthiness performances of the conventional honeycomb-filled and the hierarchical honeycomb-filled thin-walled structures under different impact conditions are systematically studied. The results indicate the energy absorption of the hierarchical honeycomb-filled thin-walled structure is higher than that of the conventional honeycomb-filled thin-walled structure, and the impact angle has significant effects on the energy absorption performance of the hierarchical honeycomb-filled structure. Specifically, the energy absorption of the hierarchical honeycomb-filled structure decreases as the impact angle increases. Lastly, multi-objective optimizations of the hierarchical honeycomb-filled structure are conducted, which is based on the RBF neural networks technique and MOPSO to maximize SEA and minimum PCF under the multi-angle oblique impact. The optimal parameter matching can improve the performance of the hierarchical honeycomb-filled structure in energy absorption. These findings can provide valuable guidelines for the design of filler structures under multiple loading angles.
