Shock testing simulates an extreme event that a unit under test is exposed to during handling, shipment, explosive event and/or daily use (e.g. dropping an object). The profile for this type of testing is defined by the shape of the time domain waveform together with its amplitude and duration. The m+p VibControl vibration control system offers full functionality for classical shock and shock response spectrum testing as well as for tests using external pulses or the capture of transient signals.
