Study on Dynamics of Micro Gas Journal Bearing--rotor System
摘要
Abstract
According to l_st order slip velocity boundary,a modified Reynolds equation for micro gas bearings was derived. Alternating--direction implication method was adopted to solve modified Reynolds equation and nonlinear gas film force was calculated. With the motion equation of rigid ro- tor, the unbalance response of the rotor system was computed and the trajectory of rotor center, time history, power spectrum and Poincare maps were calculated and the dynamics of micro gas bearing-- rotor system was analyzed. The analysis shows the existence of a complex dynamic behavior compri- sing periodic and subharmonic response of the rotor center.关键词
