【Abstract】 Based upon the Ricoati transfer matrix method and Wilson-θ integration technique, a method is presented for efficiently calculating the transient response of rotor-bearing systems. The flexible rotor supported in fluid film beamings may be excited by any arbitary force f(t) or subjected to the base excitation. Each pedestal inoludes stiffness, damping and mass properties. The proposed method is numerically stable and easy to program. Several numerical examples are given and the results show that the numerical procedure is very efficient.更多还原
