| Abstract |
In the process of penetrating a multi-layer target, the local response of charge components
is often amplified under relatively low loads. Such response amplification phenomenon may have
some influences on the pre-ignition or pre-explosion of the projectile. In this paper, a configuration
structure reflecting the basic connection characteristics of the simulated charge and shell is constructed. A theoretical model of the non-linear response for the charge with clearance structure is
established based on the configuration characteristics. The phenomenon of local response amplification is discussed from the perspective of structural dynamics. In order to further verify the phenomenon of local response amplification, simulation and test verification of the response amplification for
the simulated projectile were carried out by combining finite element numerical simulation and shaking table test. The results show that the projectile’s vibration during the penetration of a multi-layer
target may be an important factor in the local response amplification of the charge. The influence of
the vibration characteristics for the projectile’s itself needs to be considered in the impact penetration
analysis. This study has a strong reference value for understanding the problem of early unintended
ignition during the projectile penetration process. |
