摘要
高维转子-轴承系统的降维是研究转子动力学行为的关键步骤,这里着重介绍基于模态截断的后处理Galer-kin方法,并将其应用于一个双盘转子-轴承系统的降维处理。数值分析表明此方法在降低系统维数的同时保留了转子关键信息,具有较高的精度。
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.
