HFe 3 High-Frequency Dynamic Stiffness Test Rig for Elastomer Mounts

Electric and fuel cell vehicle drives present NVH specialists with new and challenging design requirements. Noises previously masked by the combustion engine are audible and more intrusive in electric vehicles. Elastomeric anti-vibration mounts influence the NVH properties of the whole vehicle. They help to enhance driving comfort and minimize noise. The HFe 3 test rig expands the dynamic testing boundaries of these elastomer mounts. Measuring the dynamic stiffness of elastomer components in higher frequencies up to 3,000 Hz becomes increasingly important when designing the acoustic characteristics of vehicles.

Applications

Characterizing a multitude of

elastomeric anti-vibrations mounts, e.g.

  • Engine mounts
  • Chassis mounts
  • Suspension bushes
  • Vibration absorbers

The HFe 3 electrodynamic test rig is tailormade to characterize the dynamic stiffness of elastomer mounts in the range of 250 to 50,000 N/mm for frequencies from 50 to 3,000 Hz. HFe 3‘s rigid design ensures resonance-free operation in an unsurpassed frequency range. It combines robust m+p measurement hardware and user-friendly m+p VibControl software to provide test professionals with a fast and efficient testing experience. m+p VibControl, the best-in-class vibration controller, is at the core of the test rig. It offers a wide range of measurement, analysis and reporting features which can be configured and updated according to your needs.

The state-of-the-art test rig technology will help you shorten development cycles by validating your simulation results on the component level, leading to fewer prototype loops and improved simulation models. The built-in industry grade automation PLC platform with its easy-to-use graphical user interface displays the state of the rig and its detailed diagnosis information, allowing all key data to be visible at a glance.

To minimize maintenance, a pneumatic air filter and condensation water separator ensuring sufficient air quality are integrated.

Benefit from HFe 3‘s versatility: The analysis of natural frequencies of vibration dampers is possible with the shaker standalone bundle, saving you a separate shaker and measurement system.

HFe 3 is engineered and designed by experts in vibration and manufactured in Germany using industry-leading components made in Germany and Switzerland. It complies with the requirements of EU Machinery Directive 2006/42/EC.

 

 

Turnkey Solution Offering High Flexibility

The modular design offers different force sensors enabling optimal results for small specimens or larger bushings, which can be changed in a blink. For high reliability and ease of use, the static tension preload can be automatically adjusted up to 8 kN using the built-in industry grade automation PLC platform.

Versatile Vibration Control System 2-in-1

In addition to basic fast random tests and widely used swept sine tests, the flexible m+p VibControl vibration control system offers stepped sine and road load for more advanced testing. The test rig’s electrodynamic shaker system can also be used for regular vibration tests without changeover.

Trustworthy, Traceable Results with Easy Reporting

All metadata for specimen and test definition are stored along with the measurement results in a single file. Exchanging data for review is easy in m+p VibControl native file formats. Export tools help to create customizable branded reports quickly and efficiently to provide demanded results in shortest time.
