Services

Tribology

The Institute of Dynamics and Vibration Research has a large number of application-specific test rigs to investigate friction and wear under real operating conditions. Highspeed Linear Friction Tester (length: 4m, velocity: 10m/s, normal load: 1kN, temperature range: -20°C - 40°C), Tribometer (velocity: 2m/s, normal load: 6kN), Rheometer (normal load: 50N, torque range: 0,5nNm - 230mNm, temperature range: -30°C - 100°C), Universal linear test-rig (length: 1m, velocity: 1m/s), Universal rotational test-rig. In addition to experimental measurement techniques, the institute offers tribological simulations with common simulation software.

Surface design and characterization

The Institute of Dynamics and Vibration Research has the necessary knowledge and experience in designing surface topographies and textures to optimize their tribological properties. In addition the institute is able to characterize surfaces using various video-based systems for a wide range of applications: optical 3D system, stereo microscope with integrated microscope camera, thermographic camera, high-speed camera.

Vibration analysis

The Institute of Dynamics and Vibration Research is able to perform high-precision measurements with a large number of specialized laser vibrometers (3D scanning vibrometer, Fiber optic vibrometer, 48-channel multipoint vibrometer, Derotator, RoboVib, 3D vibration measurement for MEMS and microsystems). In addition to the necessary sensory equipment (acceleration and force sensors), the institute also has the hardware for vibration excitation with electrodynamic shakers as well as the necessary measurement data acquisition and processing available. This enables the institute to perform experimental modal analysis, operational vibration analysis and vibration testing.

Acoustic measurement

The Institute of Dynamics and Vibration Research has a wide range of acoustic measurement equipment (microphones, laser microphones, hydrophones, acoustic camera) for measuring sound pressures in the frequency range from 20Hz to 1MHz, as well as an anechoic chamber (5.2 m x 6 m x 3.35 m).
