Mechanical Shock Test Methods

Mechanical shock testing helps determine whether a device can remain functional when subjected to sudden, abrupt motion changes associated with service environments like product handling, shipping/transportation, rocket stage separation, weapon firing, etc.

High-G Classical Shock

TheGrande shock system can produce half sine or haversine shocks in excess of 10,000G. Dual elastic accelerators boost the max velocity change to 600in/s or higher.  The system comes with pneumatic brakes and a floating seismic base to allow durations as short as .15ms.  Data is captured at 1MHz, with shock pulse amplitude and duration reported automatically. SRS plot generation is available.

Classical Shock

Classical Shock tests such as half-sine, sawtooth, and trapezoidal pulses are associated with product handling events (drop impacts) and transportation induced events (road bumps, pot holes, etc.) and are performed using our AVCO pneumatic shock table or any of our Unholtz-Dickie electrodynamic vibration systems. These shock tests are specified in the Time Domain (acceleration vs. time). Classical shock pulses up to 1,500 g can be accommodated for a wide range of test payloads.
