Calculation of a Shock Response Spectra [PDF]

open access: yesActa Montanistica Slovaca, 2011
As it is stated in the ISO 18431-4 Standard, a Shock Response Spectrum is defined as the response to a given accelerationacting at a set of mass-damper-spring oscillators, which are adjusted to the different resonance frequencies while their ...
