Shock Testing
Infinita Lab’s Shock Testing Capabilities
Infinita Lab conducts shock testing using both its pneumatic shock machine and electrodynamic shakers. Infinita Lab also has the tools needed to create and evaluate Shock Response Spectrum (SRS) shock events. Recent updates to numerous federal and military requirements call for or offer shock response spectrum testing as an alternative to the more common classical shock testing.
Our apparatus can deliver shock pulses with a maximum acceleration of 3,000 Gs. Our electrodynamic shakers may undergo shock testing while undergoing vibration testing, prior to axis rotation, significantly cutting down on test time. Our team members have performed SRS shocks for more than twenty years. At Infinita Lab, complex SRS shock profiles are our area of expertise.
Shock testing’s main objectives are:
Reliability Assessment: Shock testing assists in determining whether a system’s or product’s performance will be as expected following exposure to mechanical shocks or vibrations. It assists in locating any weak places or weaknesses that can cause errors or malfunctions.
Qualification and Certification: To assure the safety and dependability of products, many industries, including the aerospace, automotive, electronics, and military, have specific standards and rules. To prove conformity with these criteria and achieve certification, shock testing is frequently done.
Design Improvement: Engineers might find design defects, flimsy parts, or insufficient packing that need to be fixed by putting a system or product through controlled shocks and vibrations. To increase the product’s robustness and dependability, design tweaks and advancements might be made based on test results.
Shock testing can be performed as part of quality control procedures during production to make sure that products adhere to strict performance and durability standards. It assists in locating any production flaws or irregularities that can impair a product’s capacity to endure shocks.

Outline of Shock Testing
To ensure that the material can survive the relatively infrequent non-repetitive shocks or transitory vibrations experienced in handling, transportation, and service situations, shock tests are carried out in accordance with MIL-STD 810 Method 516. Moreover, shock tests are used to determine an item’s fragility so that packaging can be created to protect it if necessary and to gauge the durability of mechanisms used to secure equipment to unstable platforms.
An equipment piece will be excited by mechanical shocks to respond at both forced and natural frequencies. This reaction may result in, among other things:
- Failures brought on by changes in friction or by interference between parts.
- Dielectric strength variations, a reduction in insulation resistance, and alterations in the magnetic and electrostatic field intensities.
- Permanent deformity brought on by excessive tension.
- Accelerated material fatigue (low cycle fatigue)
