An experimental platform for the vibration characteristics of the gas turbine tilting pad bearing-rod rotor system was designed and built. The modal experiment of the rod rotor, the vibration characteristics experiment under different pre-tightening forces and the vibration control experiment based on the piezoelectric ceramic micro-displacement actuator were carried out. The experimental results showed that the bending modal frequency of the rod rotor increased with the pre-tightening force. When the pre-tightening force of the rod increased from 15 N·m to 40 N·m, the first-order and second-order modal frequencies of the rod rotor increased by 2.66% and 5.43%, respectively. The unbalance response of the tie-rod rotor system at the first two critical speeds decreased with the increase of the pre-tightening force of the tie-rod, and the increase of the pre-tightening force of the tie-rod can delay the initial speed of the low-frequency whirl of the shafting and improve the stability of the shafting. The piezoelectric ceramic micro-displacement actuator had a positive effect on the vibration control of the unbalanced response of the tie rod rotor. The relevant research results provide an experimental basis for subsequent coordinated control of coupled vibration of the rod rotor system.
