摘要：
A novel idea of using giant magnetostrictive material (GMM) based actuators for journal bearing control is presented in this paper. Frequency response tests on 619114 actuators and a,journal bearing system were examined. The performances of the system running at various journal shaft rotational speeds under control were investigated. With the aid of GMM actuators, the performances oil journal shaft positioning and vibration suppression were enhanced with the hydrodynamic effect of the oil film force inside the hearing. The results demonstrate that the novel concept is feasible and also show that GMM is an excellent material for driving function.
