| Abstract |
The TPMS lattice structure is widely utilized in the military UAV field, thus it is imperative
to investigate efficient methods for targeting the TPMS lattice structure. This paper conducts a numerical simulation to study the impact of exponential bullets on the penetration capability of lattice
structures with varying thickness and density. Specifically, the analysis focuses on the penetration
behavior of variable density Diamond structures designed using MATLAB and simulated using
ABAQUS. The simulation results reveal that as the thickness of the lattice structure increases, there is
an initial rise followed by a decline and then another increase in the increase rate of bullet velocity.
Furthermore, it is found that the position and radius of the distortion axis significantly influence bullet
velocity disparity, with deviation rates reaching 17.12 and 27.48%, respectively. Conversely, middle
plane offset has minimal impact on bullet velocity difference, with a deviation rate of only 6.38%.
These findings underscore the importance of considering adjustments to the distortion axis within a
certain range when designing UAV structures in order to enhance their penetration ability. |
