Penetration Velocity Measurement in Sands Using Magnet-Coil Gages

Abstract:

Dynamics of projectile penetration into sand depends greatly on the features of motion and state of the sand material at the interface with the projectile. The goal of this study is to clarify the behavior of projectile during penetration under the impulse loading induced by the plate impact using a vertical powder gun. In this paper, we constructed an accurate and reliable technique for measuring projectile penetration velocity into sand. “Magnet-Coil” gage method was suggested on the basis of electromagnetic induction phenomena due to movement of the projectile having magnet. We confirmed that it has sufficient measurement accuracy.
