Research on Composition and Formation Mechanism of Penetration Acceleration Signal

On the basis of the research on the penetration acceleration signal, the composition and frequency characteristic of the acceleration signal are proposed. Through the projectile hammering test, the penetrating projectile response signal is achieved and conducted with spectrum analysis to obtain the natural frequency of the projectile then comparing with the calculated natural frequency. Finally, the response signal is stripped from the test penetration acceleration signal to achieve the acceleration signal encountered by penetration resistance, which provides basis and reference for the burst control in the penetration process.
