UHF is a versatile ultra-high frequency test system designed to perform a wide range of tests, from Dynamic Mechanical Analysis (DMA) on polymers and elastomers to High Cycle Fatigue (HCF) tests on composites and metals. Thanks to its high resonance structure, low moving mass, and high dynamic performance, it ensures accurate force control even at frequencies up to 1000 Hz. These features make it the perfect tool for research laboratories and material developers who need to study viscoelastic behavior, damping properties, and fatigue resistance with high repeatability and accuracy.

UHF is an ultra-high frequency test bench developed for dynamic characterization of dampers and suspension components.
Thanks to its electrodynamic actuation and high-frequency capabilities (up to 1000 Hz), it allows engineers to analyze damping performance, response time, and hysteresis under real dynamic conditions.
Its precise force control, low noise, and compact structure make it ideal for NVH and vibration analysis, as well as for validation of motorsport and automotive suspension systems, ensuring unmatched precision and repeatability at high speed.
