Crashworthiness optimization of multi-cell hexagonal tubes under oblique impact
This paper studies the crashworthiness optimization of the multi-cell hexagonal tube under oblique impact. The linear weighted average method (LWAM) performs the optimization design of min PCF and max SEA. A detailed analysis discloses the influence of the tube parameter on crashworthy design. The wall thickness and diameter has an important influence on the crashworthiness performance of these tubes. The collapsing distances and energy absorption of these tubes are approximate if the diameter rises and the wall thickness is constant. This paper proposes a new method for fashioning the tube crashworthiness.
