Shock Control

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.

Applications

  • Classical shock testing
  • Duplicating short-duration pyrotechnic events (explosions, rocket blasts) or long-duration events at lower frequencies (earthquakes) using the shock response spectrum
  • Replicating pre-recorded time sequences (crash tests)
  • Synthesis of any pulse form
  • Earthquake simulation
  • Capture of transient signals such as drop tables or pyroshock pulses
