Couple-Stress Fluid Improves Dynamic Response of Gear-Pair System Supported by Journal Bearings
Journal of Applied Mathematics
A systematic analysis of the dynamic behavior of a gear-bearing system with nonlinear suspension, couple-stress fluid flow effect, nonlinear oil-film force, and nonlinear gear mesh force is performed in the present study. The dynamic orbits of the system are observed using bifurcation diagrams plotted using the dimensionless rotational speed ratio as a control parameter. The onset of chaotic motion is identified from the phase diagrams, power spectra, Poincaré maps, Lyapunov exponents anddoi:10.1155/2012/527878 fatcat:i2dwbjmfurfubmwzem7podkrb4
