VB Tech’s MDOF (Multi-Degree-of-Freedom) vibration test systems are engineered to accurately replicate the complex, multi-axis forces that products encounter in real-world environments. With force capacities from 10kN to 60kN and test table dimensions up to 1500mm x 1500mm, these systems are used across industries that demand precision, including aerospace, defence, automotive, and advanced transportation.
MDOF systems simulate conditions that go far beyond the limitations of single-axis testing—allowing for the evaluation of structural integrity, mechanical resilience, and functional reliability under dynamic and unpredictable load conditions. These systems are particularly suited for testing satellite payloads, aircraft engines, docking systems, and critical onboard electronics.
VB Tech’s MDOF shakers are driven by high-efficiency SAP Series Class D amplifiers and designed according to our RAICE philosophy—delivering Reliability, Accuracy, Intelligence, Cost-effectiveness, and Energy-efficiency. The SAP Series amplifiers independently power each shaker, which delivers over 93% efficiency, minimizing power consumption, heat generation, and operational costs.
Typical applications include simulating aerodynamic forces during flight, assessing landing and braking resilience, spacecraft docking verification, structural flutter analysis, and vibration testing for tanks, cars, rail systems, and even earthquake simulations. As missions extend to deep space, these systems will continue to play a critical role in ensuring mission readiness and survivability.
