Abstract

© 2020, The Author(s). This paper investigates the effects of tangential harmonic excitation on the friction-induced-vibration in multi-degree-of-freedom systems that are coupled in the tangential and normal directions. A minimal two-degree-of-freedom system and a more complicated slider-on-disc system are considered. It is observed the friction-induced-vibration of the systems can be suppressed with the tangential harmonic excitation when the amplitude and frequency of the excitation are in certain ranges. The analytical method to determine the ranges where the systems are stabilized by the tangential excitation is established. To verify the analytical results, a great amount of computational effort is also made to simulate the time responses of systems in various combinations of values of the amplitude and frequency, by which the parameter ranges where the friction-induced vibration is suppressed can also be obtained. This research can provide theoretical guidance for the suppression of friction-induced-vibration in a real disc brake system by application of a tangential harmonic excitation.
