    Abstract
  • In order to investigate the influence of projectile structure design on the detonation reliability, a low-cost and portable static test device for fuze-warhead coordination is designed in this paper to carry out the tests of detonation transfer margin under different conditions. Based on the moving least square method, the multivariable response function is constructed to evaluate the detonation reliability and quantitatively analyze influence of the sensitive factors and coupled effects. The results indicate that the gap distance and the thickness of inert buffer layer have more significant impact on the detonation of the warhead charge while the influence of the interlayer thickness is relatively small within the preset range of 3–5 mm. To ensure the reliability of kinetic energy penetrators under ambient temperature, the relative position of fuze, the interlayer thickness, the gap distance and the thickness of inert buffer layer should not exceed 25, 3.5, 25, and 22 mm, respectively. The test device, analysis method and research results will provide a good reference and guideline for structural design and reliability verification of kinetic energy penetrators.
