| Abstract |
Non-ideal high-speed rotors often exhibits nonlinear jumps driven through a power drive with limited capacity. The study of nonlinear jump in such rotor system is of considerable current interest. These systems often get destabilized on exceeding a critical input power proximity to resonance. This phenomenon is known as the Sommerfeld effect. The present study investigates the dynamics of a disk mounted non-centrally on a flexible shaft driven through a brushed DC motor. Additionally, cross-coupled external and internal damping both are considered for the present study. The steady-state and transient analysis of the proposed system reveal a couple of interesting facts about the complex interaction of the gyroscopic rotor with the motor. |
