Two novel H-shaped whip restraints integrating multi-cell configurations with surface perforations were developed to enhance energy absorption and stabilize peak reaction forces. Finite element analysis was conducted using ABAQUS/Explicit to compare mechanical responses between conventional honeycomb H-shaped restraints and multi-cell perforated thin-walled structures under axial/eccentric compression. Results showed the conventional structure exhibited 20% higher initial peak crushing force than new designs, while the 25-cell elliptical-hole configuration demonstrated optimal performance with 21.7% greater total energy absorption. During eccentric loading, the conventional design showed rapid load escalation beyond 120mm displacement, whereas the multi-cell perforated structure maintained stable platform force fluctuations. Crashworthiness tunability was achieved through series-parallel topology optimization of cellular units, enabling directional control of energy absorption via cell quantity adjustment and layered configuration design.
