| Abstract: | The dimension reduction of the High dimensional rotor-bearing system is a key problem in the study of dynamical behavior of rotor.The post-processed Galerkin method is proposed in terms of the model truncation and employed to deal with the dimension reduction of a rotor-bearing system with two disks.Numerical analysis shows that the post-processed Galerkin method is valid in dealing with the dimension reduction of the rotor-bearing system and has a higher accuracy. |
