摘要：
Studying effects of 93W tungsten alloy fragments on ballistic limit (V50) of aluminum alloy target plate is of important significance for power design of warhead damage elements. Here, ballistic limits (V50) of tungsten alloy cube fragments and spherical fragments penetrating a 4 mm 2024 aluminum target at a 90° angle of impact were obtained through ballistic impact tests. Based on the consistency between numerical simulation and test results, effects of tungsten alloy fragment shape and mass on V50 were analyzed. The results showed that penetration V50 values of fragments with two different shapes decrease with increase in fragment mass; penetration V50 value of cube fragment at impact angle of 90° is lower than that of spherical fragment, and the difference between both V50 values increases with increase in fragment mass; due to variation of target attitude, cube fragment causes Vso having a fluctuation range; with increase in fragment mass, fluctuation range of V50 relatively increases, and the probability for cube fragment' s V50 being less than that of spherical fragment also increases. © 2023 Chinese Vibration Engineering Society.
