Abstract
Experimental tests and numerical simulations are performed to explore the influence of damping components with slotted surface structures in a friction system on the dynamic instability. Damping components with slots at different depths are designed, combined with a special tribological test apparatus to evaluate their ability to stabilize the friction system. The experimental results show that damping components with a slotted structure can dramatically reduce the vibration response of the system and the energy level at the dominant frequency, thus stabilizing the friction system. Specifically, the system containing shallow slots on the leading edge rather than the trailing edge can eliminate the tangential partial wear and show the greatest potential on reducing the unstable vibration, which can be further verified by finite element analysis. Moreover, it is found that the contact inclination angle between the disc and the pad plays an important role in the generation of instability of the system, which can be further explained through a two degree of freedom model with a contact inclination angle.
