Abstract

Abstract

A finite element model was established for the head car of a high-speed train and its crashing progresses with a rigid wall at different speeds, simulated by using LS-DYNA software. It is found that when a crash occurs the draft sill deforms mainly in the Euler bending mode, which is harmful to buffering and energy absorption. Based on the understanding from the crashworthiness analysis of the original design, we propose to redesign the structure of the draft sill through adding square tubes with round corners as energy-absorbing tubes, which are either filled with aluminum foam or not. Two different sizes are chosen, thus four schemes are formed. The results of numerical simulation show that, compared to the original design, the energy absorption capacity in all of the new schemes has greatly improved, and the peak force on the rigid wall decreases in a certain extend. The scheme with the tubes having large radius of round corner, thick thickness and aluminum foam filler has the most obvious improvement.
