摘要
The dynamic characteristics of a general bearing assembly have been studied by using Finite Element Method and G-H Method. A rotcr bearirg system with distributed parameters of rigid disks and bearings was analyzed by Finite Element Method. The characteristic equaticn of the rotor bearing systern was given, and the generalized eigenvalue problem was solved by transfering that defined by one real symmetric matrix and one skew symmtric matrix into one defined by two real symmetric matrices. Whiring speeds and vibration shapes of rctor bearing systems under different spin speeds were obtained and so the natural frequencies of the rotor bearing systems could be obtaincd.
