@article{(Open Science Index):https://publications.waset.org/pdf/16386, title = {Chaotic Response and Bifurcation Analysis of Gear-Bearing System with and without Porous Effect under Nonlinear Suspension}, author = {Cai-Wan Chang-Jian}, country = {}, institution = {}, abstract = {This study presents a systematic analysis of the dynamic behaviors of a gear-bearing system with porous squeeze film damper (PSFD) under nonlinear suspension, nonlinear oil-film force and nonlinear gear meshing force effect. It can be found that the system exhibits very rich forms of sub-harmonic and even the chaotic vibrations. The bifurcation diagrams also reveal that greater values of permeability may not only improve non-periodic motions effectively, but also suppress dynamic amplitudes of the system. Therefore, porous effect plays an important role to improve dynamic stability of gear-bearing systems or other mechanical systems. The results presented in this study provide some useful insights into the design and development of a gear-bearing system for rotating machinery that operates in highly rotational speed and highly nonlinear regimes. }, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {7}, number = {7}, year = {2013}, pages = {1400 - 1405}, ee = {https://publications.waset.org/pdf/16386}, url = {https://publications.waset.org/vol/79}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 79, 2013}, }
