Shock Testing Capabilities at Compliance Management Group
Compliance Management Group offers shock testing on our electro-dynamic shakers as well as through the use of our pneumatic shock machine. Additionally, Compliance Management Group possesses the necessary equipment to produce and analyze Shock Response Spectrum (SRS) shock events. The latest revisions of many federal and military specifications are requiring, or offering, shock response spectrum as an alternative to typical classical shock testing.
Our equipment is capable of delivering shock pulses exceeding 900 g’s. Shock testing on our electro-dynamic shakers can be performed during vibration testing, prior to axis rotation, 大大减少测试时间.
Our staff has over twenty-five years of experience in the performance of shock and vibration related testing.

Shock Testing Overview
Shock tests, per MIL-STD 810 Method 516.5, are performed to assure that material can withstand the relatively infrequent non-repetitive shocks or transient vibrations encountered in handling, transportation and service environments. Shock tests are also used to measure an item’s fragility, so that packaging may be designed to protect it, if necessary, and to test the strength of devices that attach equipment to platforms that can crash.
Mechanical shocks will excite an equipment item to respond at both forced and natural frequencies. This response, among other things, can cause:
- Failures due to increased or decreased friction, or interference between parts.
- Changes in dielectric strength, loss of insulation resistance, vibrations in magnetic and electrostatic field strength.
- Permanent deformation due to overstress.
- More rapid fatiguing of materials (low cycle fatigue)
