Simulation-Based Design of Parametric Origami Structures for Blast and Ballistic Protection

Abstract

This paper investigates the use of parametric origami structures as multifunctional protective layers for lightweight armoured vehicles. Three geometries—Miura-Ori, Kresling, and Waterbomb—were developed as fully parametric CAD models and evaluated under different threat scenarios. Finite element simulations were performed to assess their structural response to vertical blast loads, lateral shaped-charge impacts, and vibrational excitation. Results show that the Miura-Ori panel reduces transmitted acceleration by 58% under simulated IED conditions and provides vibration damping up to 0.82 mm at the center. The Kresling configuration absorbs lateral shocks with 45% pressure attenuation through controlled torsional collapse. The Waterbomb matrix reduces vibroacoustic amplitudes by over 20% across the 100-800 Hz range. A 3D printing orientation study was also conducted, revealing the need to optimize supports for manufacturability. The study confirms that origami-based, parametrically driven designs offer promising performance-to-weight advantages and adaptability for modular armour systems.
