Aimed at the problem of how to determine the issue of cut-off frequency filter

in processing penetration overload acceleration signal

the finite element ANSYS software is presented to analyze model shape of the kinetic energy projectile.Penetration overload acceleration signal is filtered by low-pass filtering in order to determine the rigid body overload.The choice of filter cut-off frequency should be on the basis of projectile vibration model shape analysis and the frequency spectrum of the measured penetration acceleration signal.Through live-fire testing

the acceleration signal in the process of kinetic energy projectile penetration plate is successfully measured and provide an important basis for the design of intensity of projectile structure and fuse structure.
