Abstract EN
This paper addresses the self-excited vibration problems of maglev vehicle-bridge interaction system which greatly degrades the stability of the levitation control, decreases the ride comfort, and restricts the cost of the whole system.
Firstly, two levitation models with different complexity are developed, and the comparison of the energy curves associated with the two models is carried out.
We conclude that the interaction model with a single levitation control unit is sufficient for the study of the self-excited vibration.
Then, the principle underlying the self-excited vibration is explored from the standpoint of work acting on the bridge done by the levitation system.
Furthermore, the influences of the parameters, including the modal frequency and modal damping of bridge, the gain of the controller, the sprung mass, and the unsprung mass, on the stability of the interaction system are carried out.
The study provides a theoretical guidance for solving the self-excited vibration problems of the vehicle-bridge interaction systems.
