| Abstract |
Based on the typical characteristics of the actual projectile structure, a configuration structure reflecting the basic connection characteristics of the simulated charge and shell is constructed. Based on the Hertz contact theory and the concentrated mass method, the collision vibration model of the charge with clearance structure is established. The 4th order Runge-Kutta method is used for the theoretical solution. The response plots, phase diagrams and poincare cross section of the system are analyzed for different stiffness and damping of the charge. The non-linear vibration characteristics of the simulated projectile structure were verified by combining FEM numerical simulations and vibration tests. The results show that the local response amplification of the projectile often occurs during the penetration through the multi-layer target at relatively low loads. The structural vibration may be an important factor. The stiffness and damping have a significant influence on the vibration characteristics. This study has a strong reference value for understanding the problem of early unintended ignition during projectile penetration. |
