...Yahui Cui; Zhansheng Liu; Yongliang Wang; Jianhuai Ye To investigate the effect of oil film force on a geared rotor system, a short journal bearing model was applied to represent nonlinear oil film force. A dynamic model of the geared rotor oil journal bearing system was presented. The nonlinear...
