Failing Your Vibration Testing?
Don’t keep re-testing blindly. We identify the failure mechanism, engineer the fix, and verify the outcome - so your product passes the vibration test.

Lessons Learned from Real Testing
We’ve spent days inside TÜV, TRaC (Element) and PARC. When a product fails, the test house logs it—but they don’t fix the design. That’s where we come in.
Why Products Fail Vibration Tests
The real value is understanding how and why a structure responds. Failures reveal weaknesses that can be designed out - that’s the service we provide; we help you succeed.
- Mode shapes coinciding with excitation frequencies
- Fixture stiffness errors or unrealistic boundary conditions
- Incorrect isolation tuning or damping
- Fastener preload loss and local stress raisers
- Asymmetric mass or stiffness distribution
Standards & Experience
- MIL-STD-810
- RTCA/DO-160
- ISO and IEC (various)
- API 619, ISO 20816, VC-C/VC-D, BS 5228
We don’t just run tests - we write test plans, investigate failures, and rectify designs to pass certification.
What We Do
- Test planning & procedures
- Instrumentation & calibration
- Fixture/boundary evaluation
- Sine, random, shock, mixed-mode testing
- Modal & operational measurements
- On-site troubleshooting
- Analysis, reporting, and design rectification support
Our Process
Investigate → Test & Measure → Analyse → Design → Support
Investigate
Define the problem and what “good” looks like.
Test & Measure
Capture repeatable data. The same engineer measures and analyses.
Analyse
Turn data into evidence-based understanding.
Design
Engineer the fix. We use FEA to simulate responses—but experience makes the difference.
Support
Witness re-tests, confirm compliance, support in service.
