Noise Emission Tester
Noisy, Noisy, Noisy
The DKNT enables quick and easy investigation of friction behaviour and friction-induced noise at low speeds and linear oscillating movements. With a robust system of reliable linear actuators for applying normal force and a permanent magnet servo motor for the main drive, the test bench delivers precise and reproducible results.

Low Noise Level vs. High Noise Level
Developed as a test bench for comparative studies, the set-up effort, test execution and documentation and analysis of results are designed to be highly user-friendly. As a result, the test rig guarantees a high degree of friction differentiability and repeatability of results.
Screenshots of a measurement with low and one with pronounced noise development. The system differentiation is easily possible due to the differences in intensity in the waterfall diagrams, among other things.
