The Influence of Shaft’s Bending on the Coupling Vibration of a Flexible Blade-Rotor System

Figure 22

Mode shapes of rotor-blade coupling system due to the rotational speed.

(a) Mode of blade (100 rad/s)

(b) Mode of blade (1000 rad/s)

(c) Mode of rotor (100 rad/s)

(d) Mode of rotor (1000 rad/s)
