Friction-Induced Vibration of a Mass-On-Belt System with Intermittent Contact Detachment 2019-01-1595
A well-known mass-on-belt model is employed to study self-excited vibration due to mode-coupling. The model is employed to study mode-coupling as one of the major instability mechanisms in frictionally driven systems. Nonlinearity stems from discontinuity due to dependence of friction force on relative mass-belt velocity and mass-belt contact detachment during oscillation.
Eigenvalue analysis is carried out to determine the onset of instability. Within the unstable region, four possible phases that include slip, stick, separation, and overshoot, are found as possible modes of oscillation. Numerical analyses are used to investigate the effect of two dimensionless parameters related to belt velocity and normal load on the steady-state response of the system. The behavior of the system is thoroughly discussed and the minimum normal load to prevent separation is provided in the closed form.
