DISCOVER THE UHFTS SYSTEMS

ONE SYSTEM, MANY APPLICATIONS

UHFTS is a versatile ultra-high frequency test system designed to perform a wide range of tests, from Dynamic Mechanical Analysis (DMA) on elastomers to NVH testing on dampers. 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. This makes it ideal for both research laboratories and industrial validation environments, where precision, repeatability, and reliability are essential.

Features

Test frequency up to 1000 Hz
Dynamic loads up to 4.6 kN
Maximum speed of 5 m/s
Based on high-performance electrodynamic actuators
Dedicated software: automated DMA test management, frequency analysis and reporting with Test Center
High resonance structure: minimises vibrations and resonances, and allows the installation of a variety of actuators

Applications

Dynamic Mechanical Analysis (DMA)
Noise, Vibration and Harshness (NVH)
High Cycle Fatigue Tests (HCF)
Fracture Mechanics
Vibrational analysis of components

Advantages

Interchangeable actuators on the same frame: the modular design allows different actuators to be mounted on the same structure, allowing for enhanced load capacity when required.
Fully electric: no hydraulic oil, no leaks, no contamination risks.
Exceptional control accuracy: precise management of force and displacement even at 1000 Hz.
Quiet and compact operation: ideal for laboratory environments and NVH applications.
High dynamic response: perfect for characterising viscoelastic materials or testing dampers at realistic excitation frequencies.

XUD SERIES

ULTRA-HIGH DYNAMIC TESTING SYSTEM

At STEP Lab, we have designed the XUD series to perform high dynamic dynamic tests with accelerations of up to 100 G and frequencies of up to 500 Hz, offering exceptional performance in short duration and high intensity tests.

Applications

Materials testing (Elastomers, composites, metals, etc.)
Shock absorber high dynamic tests
Characterization damper testing
High strain rate tests up to 6 m/s

Features

Closed loop control of force and displacement by Test Center control system
Reproduction of sinusoidal, triangular and custom profiles
High resolution data acquisition (24 bit)
Variable installation positions
Controller in separate and free position
Flexible programming of test sequences by Test Center graphic interface
Large variety of grips, testing tools and load cells
Integration with extensometers and climatic chambers

Advantages

Exceptional dynamic performance
Maintenance tending to zero thanks to the absence of a mechanical transmission
Low power consumption thanks to the high efficiency of the electric motor and absence of mechanical transmission
Possibility to manage up to 10 actuators in syncronised mode so as to create a 4-poster system
Flexible geometrical configuration: machine can be purchased as a linear actuator without upper crossbeam columns
Wide range of use thanks to programmable speed up to 6.000 mm/s and high stroke over 200 mm
Easy installation thanks to the request of only one electric socket and compressed air
