Qualification testing is critical to mission success, but traditional vibration test methods can lead to overtesting, hardware damage, and costly delays.
The Quartus Force-Limited Vibration Fixture (FLVT) is a ready-to-deploy, plug-and-play force-limited vibration testing system that limits loads in real time to protect sensitive spacecraft and hardware. Built as a commercial off-the-shelf (COTS) solution, FLVT combines precision mechanics, integrated electronics, and standardized interfaces for consistent, repeatable results across aerospace, defense, and advanced hardware programs.


Overtesting is one of the most expensive and avoidable risks in vibration qualification.
- Simpler acceleration-based random vibration tests often create unrealistic force loading.
- Standard force-limited vibration testing (FLVT) methods reduce risk but typically require custom engineering, costly integration, and expert tuning.
- Many teams lack resources or access to a fixture capable of real-time force and moment summation.
Quartus developed FLVT to remove these barriers, bringing reliable, configurable, and affordable force limiting to any test environment.
With Quartus FLVT, teams can conduct force-limited vibration testing quickly and confidently without custom integration or specialized electronics.
The Quartus FLVT integrates mechanical, electrical, and analytical innovation into a single deployable system. Designed from the ground up for simplicity and reliability, it arrives pre-calibrated and ready to operate — no custom engineering required.
