Our testing laboratory conducts investigations of stick-slip behavior professionally and in accordance with international, including accredited standards.
The stick-slip effect (also referred to as “creep” or “squeak” behavior) is a physical phenomenon in which motion does not occur smoothly but is characterized by alternating “sticking” and “slipping” at contact surfaces. Under real-world conditions, this can affect motion and noise behavior, force requirements, the tactile perception of surface interactions, and dynamic friction, potentially leading to noticeable disturbing noises.
The tribological tests carried out in our laboratory evaluate the start-stop, sticking, and sliding behavior of contacting surfaces in relative motion and provide fundamental information on dynamic friction properties that go beyond conventional static friction measurements.
During tribological testing, standardized specimens or component assemblies are moved relative to each other under defined normal loads, speeds, surface pairings, and temperature/humidity conditions. The measured force and displacement profiles are analyzed to determine characteristic values such as the static and kinetic friction coefficients, the difference between static and dynamic friction, and any abrupt stick-slip transitions.
Stick-slip behavior is a critical factor in assessing sliding performance, smoothness of motion, noise generation, and required actuation forces in technical systems and products. Typical applications range from automotive and railway engineering to furniture and door guidance systems, as well as tribological challenges in medical, precision, and industrial devices.
In the following a list of standardized Stick-Slip tests offered, including accredited methods such as VDA 230-206 or procedures according to automotive industry standards (Volkswagen, BMW, Ford, etc., materials including leather, coated textiles /„synthetic leather“). Additionally, FILK has extensive long-term experience in this field through research and development, making it an ideal partner for scientific or technical inquiries.
