Abstract

In order to study the vibration characteristics of a cracked rotor system, a finite element model of a cracked rotor system was established. The rotor experiment platform was built to verify the correctness of the finite element model, and then the influence of depth on the vibration characteristics of the rotor system was studied. The results show that with the increase of the crack depth ratio, the vibration response of the rotor system becomes stronger in both directions, the frequency domain curve has higher frequency multiplication, and the axis center trajectory becomes larger. If the crack depth ratio is further increased, the rotor system vibration may be lost steady.
