Shock Control

Shock testing simulates an extreme event that a unit under test is exposed to during handling, shipment and/or daily use (e.g. dropping an object or exposure to an explosive event). 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.
