Shock & Vibration Testing

X-ES engineers perform exhaustive qualification testing to verify that our products can withstand high levels of shock and vibration. Throughout the design and development process, engineers evaluate the results of shock and vibration tests to understand the likely impact of environmental forces and ensure that each product shows the expected durability for its ruggedization level. Every deployable unit delivered is subjected to environmental stress screening (ESS) at levels based on customer needs.

We perform on-site shock and vibration tests with two electrodynamic shakers, including:

  • An Unholtz-Dickie electrodynamic shaker with a 36 in. square slip table capable of performing:
    • Half-sine, sawtooth, gunfire, and shock response spectrum (SRS) shock tests for both functional and crash safety shock pulses.
    • Swept sine, random, and sine-on-random (SOR) vibration tests at force levels up to 80.1 kN (18,000 lbf).
  • An LDS V850 electrodynamic shaker capable of performing:
    • Half-sine and sawtooth shock tests for both functional and crash safety shock pulses.
    • Swept sine, random, and sine-on-random (SOR) vibration tests at force levels ranging from 8.9 to 22.2 kN (2,000 to 5,000 lbf).
