Abstract

Abstract: In order to investigate the anti-penetration performance of target plate of the same thickness under different number of layers, a model of SPH(Smoothed Particle Hydrodynamics) cylindrical bird bullet to impact 2024 aerospace aluminum alloy Lagrange target is established by using the AUTODYN finite element software. The thickness of target is 1 mm, 2 mm, 3 mm and 4 mm, 1 mm and 2 mm target plate is divided into single and double, 3 mm target plate is divided into single, double and three layers, 4 mm target plate is divided into single, double and four layers. By comparing the bulge height, the influence of target thickness and number of target layers against bird strike are discussed. The performance of the target against bird strike is enhanced with increasing target thickness with the help of research results. Moreover, for the 1 mm, 2 mm, 3 mm plate, the performance against bird strike is declined with the increment of the number of layers. However, the performance of 4 mm plate is enhanced.
