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

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.
