  • Method of and device for determining a time-dependent gradient of a shock wave in a ferromagnetic element subjected to a percussion load
    Patent number: 6356077
    Abstract: A method of determining a time-dependent gradient of a shock wave in a percussion or subjected to a percussion load ferromagnetic element and including subjecting the ferromagnetic element to action of a magnetic flux, providing a voltage measuring instrument associated with the ferromagnetic element for determining a change of a magnetic flux velocity, which is determined as a change in a measuring voltage, during a percussion action, and determining the gradient of the shock wave by additive superimposition of the measuring voltage; and a device for effecting the method.
