• According to the WHO 2022 report on world traffic injuries, 1.3 million fatalities and 39 million injuries occur globally.
• In automobile crash zones, impact absorbers are placed between the bumper and side rails of the vehicles, which are widely used to absorb kinetic energy through plastic deformation.
• However, the design of the impact absorber determines the crashworthiness of the vehicle structure.
• In general, automotive industries mainly aim to reduce vehicle weight to meet the safety standards set by Federal Motor Vehicle Safety standards.
• For low-cost and high strength-to-weight ratios, aluminum, steel and fiber-reinforced composites have been mostly used in the fabrication of crash-boxes.
• Currently, existing systems have tried to address this problem. However, their scope was limited to the use of micro-lattices, and glass sponge to derived tubular structures for lightweight applications.

• The present invention discloses a system and method for a bionic impact absorption device (as shown in Fig. 1).

System

1. The system comprises comprising at least one bionic tube (102) for absorbing high impact energy.
2. The bionic tube (102) comprises at least two relatively closed cell and at least two relatively open cell, forming at least one-unit cell (104).
3. The one-unit cell (as shown in Fig.2 & 3) comprises at least one horizontal strut (110) for providing strength, one diagonal strut (112) for providing buckling resistance, and at least two vertical strut (114) for providing strength.
