2D Tribo-Acoustic Test System
2D Tribo-Acoustic Test Bench

Analysis Of Stick-Slip, Friction And Sliding Noises, Material Damping, Abrasion And Wear

The MB Dynamics 2D Tribo-Acoustic test bench enables the testing of diverse material pairings and components under real, highly dynamic relative motions and normal forces. It is designed to analyse friction, friction noise, stick-slip phenomena, material damping, and abrasion and wear. By precisely replicating real dynamic load conditions, it offers more accurate predictions of practical stick-slip risks and enables a more precise analysis of abrasion and wear.

2D Tribo-Acoustics Test System

The 2D Tribo-Acoustic Test Bench design is entirely friction-free, and the actuators operate with extremely low noise, allowing direct measurement of frictional forces and accelerations at contact surfaces without interference from additional leaf spring elements or friction in drive and guide components. The test bench supports stick-slip tests using specified RANDOM excitation profiles (PSDs, such as those outlined in GMW 16321) and tests with constant relative speeds and normal forces (e.g., VDA-230-206, FORD CETP01.05). Standardised sample holders with leaf springs are available for VDA 230-206 tests. Additionally, tests can be conducted with the addition of oils, lubricants, greases, various liquids or pastes, as well as dirt and dust, as an optional feature.
