Shock Response spectrum Vs extreme response spectrum

In what context?

Extreme response and shock response spectra both offer the greatest response of

a single degree-of-freedom linear system based on its own frequency, for a given

Q factor, when submitted to vibration or the shock to study (we do not use the

definition of ERSs from three times the rms value of the response). The calculation

algorithm is the same.

In the case of long term vibrations, this response occurs during the vibration: we

only focus here on the primary spectrum.

In the case of shocks, on the other hand, the largest response peak can occur

during or after the shock. We generally use the envelope spectrum of primary and

residual spectra. It is the only difference between ERSs and SRSs.
