The dynamic analysis of a vibrating rotor-stator rubbing in an inviscid fluid is studied in this experimentally paper. The unbalanced rotor system is widely used in rotordynamic, and unbalance-rubs coupling fault is essential and can occur simultaneo

Taking into account the coupling effect of a viscous fluid and a vertical rotor in permanent contact with a fixed stator has proven to be a complex and challenging task in fault diagnosis. In this paper, an isotropic vertical rotor-stator model that
