摘要
Abstract
In order to study the penetration resistance of the corrugated aluminum plate filled with ceramic rod composite structure under different impact positions,a multi-ceramic-rod reinforced composite structure composed of trapezoidal corrugated aluminum plate was designed,followed by ballistic impact test and numerical simulation.By comparing the failure mode,energy absorption efficiency and velocity variation patterns under different impact points,the anti-penetration mechanism of the structure at three typical positions was obtained.The results show that the energy absorption of the multi-ceramic-rod reinforced trapezoidal corrugated aluminum plate is composed of the crushing energy dissipation of the ceramic panel,the shear expansion and plastic deformation of the trapezoidal corrugated aluminum plate,the fracture and crushing of multiple ceramic rods,and the tensile failure of the PE backplate.The ballistic resistance exhibits significant position-dependent characteristics,particularly influenced by ceramic rod spatial distribution and backplate support capacity.In composite structures,compared the midpoints of the upper and lower bases of the trapezoid with the midpoint of the oblique side,the protective area of the ceramic rod is larger,the ceramic crushing area is larger,and the anti-penetration ability is stronger.During high-velocity penetration of the target plate,due to the common constraints of the aluminum plate and the PE backplate behind the ceramic rod,the ceramic fragmentation near the midpoint of the lower base is more thorough compared to the upper base,leading to a further improvement in anti-penetration performance.The anti-penetration ability is improved,resulting in 20.45%and 8.14%increases in ballistic limit velocity compared with the other two places.The research results provide a theoretical guidance for the design of the reinforced corrugated structure.关键词
