Paper Title:
Nonlinear Analysis of Porous Squeeze Film Damper-Mounted a Rotor with Non-Linear Suspension and Roughness Effect
  Abstract

This work studies a numerical research undertaken to investigate the dynamic behaviors of porous squeeze film damper mounted a rotor considering longitudinal and transverse roughness effect under nonlinear suspension. The dynamic response of the rotor center and bearing center are studied. The analysis methods employed in this study are inclusive of the dynamic trajectories of the rotor center and bearing center, Poincaré maps and bifurcation diagrams. The maximum Lyapunov exponent analysis is also used to identify the onset of chaotic motion. The modeling results provide some useful insights into the design and development of rotor-bearing system for rotating machinery that operate in highly rotational speed and highly nonlinear regimes.
