Rub-Impact Detection in Rotor Systems with Pedestal Looseness Using a Nonlinearity Evaluation

In this paper, a nonlinearity evaluation is proposed in order to identify the rub-impact in rotor systems with pedestal looseness. Nonlinear mathematical models have been established for bearing-rotor systems with single pedestal looseness and pedestal looseness coupled with rub-impact. Piecewise li...
