Classical Shock tests such as half-sine, sawtooth, and trapezoidal pulses are performed using our AVCO pneumatic shock table (Figure A) or any of our many Unholtz-Dickie electrodynamic machines such as our Model T2000 Shaker (Figure B: T2000 Shaker). Classical shock pulses up to 1,500 g can be accommodated for a wide range of test payloads. A typical classical shock pulse is shown in Figure C (300 g half-sine pulse, 3 msec duration).

SRS Shock tests over the frequency range to 10 KHz are performed using our T2000 / R16C / S092 electrodynamic shakers rated up to 3000 g. A typical SRS Shock profile is shown in Figure E (3,000 g out to 10,000 Hz).

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.

Classical Shock These tests are specified in the Time Domain (acceleration vs. time) in the form of pulses typically called out as half-sine, sawtooth, or trapezoidal waveforms among others. Classical shock pulses typically are associated with product handling events (drop impacts) and transportation induced events (road bumps, pot holes, etc).

Mechanical Shock

SRS Shock These tests are specified in the Frequency Domain in terms of acceleration (g) vs. frequency (Hz) and typically are associated with high-g environments caused by severe impacts, explosive events, etc. SRS (shock response spectrum) transient shocks incorporate a broad range of frequencies into the test pulse which better approximate the real mechanical event. SRS shock is sometimes called “pyroshock” because the high-g environment being simulated is often generated by an explosion (pyrotechnic event).
