Nonlinear Dynamics of a Blade Rotor with Coupled Rubbing of Labyrinth Seal and Tip Seal

Figure 10

Bifurcation diagrams of the periodic response of coupled rubbing of the blade rotor: (a–k) the bifurcation diagrams with the rotor rising up; (l) the bifurcation diagram with the rotor slowing down. US means the unstable solution, SP means the static bifurcation point, HP means the Hopf bifurcation point, and DP means the periodic doubling bifurcation point.
