NONLINEAR VIBRATION OF A MOVING BODY CAUSED BY FRICTION

X.-Z. Zhang, D. Zhai, J. Dong
Abstract:
The nonlinear phenomenon of the vibration of a rotating machine is studied experimentally and numerically. The rotating part of the machine has a contact surface with static elastic surface. Vibration of the rotating part itself without any contact to the surface is considered as linear problem. Inviting frictions on the contact surface causes nonlinear phenomena, which cannot be explained by linear concepts, such as multiple attractors, chaotic orbits and bifurcation behavior.
The experiment is focussed the influence of the friction on the behavior of the rotating part. With the help of the mathematical analysis, the mechanism of the influence is understood. The result obtained offer an engineering solution using nonlinear concept.
