The Application of Vibration Recording and Analysis in Tribological Research on Sliding Friction
The paper reports on a tribological research on the macroscopic manifestation and characteristics of sliding friction. The aim of the task was to measure friction in lubricated sliding contacts and test the interactions between the environment (the test rig) and the experimental friction contact. Friction-induced vibrations were observed and studied as a manifestation of the process. The typical set of velocity and force/torque transducers was supplemented with a multi-channel vibration detection system. The vibro-diagnostic augmentation of the tribological experiment gave a new insight into the nature of motion of the system and load–velocity–friction relations. Modes of operation of the system were identified by spectral analysis in confrontation with natural frequencies of vibration of the test rig’s sub-systems.
