This study presents a method for analyzing and predicting the jump phenomena of a sliding bearing. The nonlinear behavior is caused by a discontinuity on the stiffness. These conditions are due to the number of rolling elements in contact and the backlash along the perpendicular direction of the motion.
It is shown here that the nonlinear stiffness of the sliding bearing presents jump phenomena. A detailed analysis of the nonlinear stiffness parameters and its effects on the jump conditions are included. In this paper only large displacements are considered.
Numerical results are compared to time domain measurements where the nonlinear behavior is clearly identified. This comparison shows under which condition the system behaves almost as a linear system, whereas under which conditions it behaves highly nonlinear.
