Synthese des Schockantwortspektrums (SRS)

A vibration control feature used to synthesize a specified shock response spectrum (SRS) to measure a payload’s resistance to shock damage.

SRS synthesis is used to evaluate the shock resistance of the DUT (device under test). This is achieved by synthesizing, within a closed-looped test system, a user-specified SRS profile of acceleration versus frequency in order to create complex transient waveforms for driving an electrodynamic shaker. The desired SRS profile is sometimes referred to as RRS (required response spectrum).

The test system takes advantage of the fact that many different transient waveforms can produce the same SRS profile; hence, parameters can be selected to account for the shaker’s capabilities and for likely damage to the DUT.
