Figure 6

Output responses measured for the rotor with and without impact during the transient rotation.

(a) Output measured along the x direction of the bearing B₁

(b) Output measured along the z direction of the bearing B₁

(c) Output measured along the x direction of the bearing B₂

(d) Output measured along the z direction of the bearing B₂

(e) Output measured along the x direction of the bearing B₃

(f) Output measured along the z direction of the bearing B₃
