Numerical analyses on dynamic control of five-degree-of-freedom maglev vehicle moving on flexible guideways

This paper presents numerical analyses on dynamic behavior of a maglev vehicle with a control system moving on flexible guideways. The vehicle is simplified as a body with the primary and the secondary suspension parts and has five-degree-of-freedom (d.o.f.). So, its five kinds of motions, i.e., heave, sway, pitch, roll, and yaw motions are considered. The numerical results show that the dynamical characteristics of a coupling maglev vehicle/guideway system are different from those of the uncoupling system in which the deformation of the guideways is neglected. For the coupling system, one kind of disturbances in the five motions may excite several other kinds of moving responses. Both the disturbances and the control parameters have an influence on the stability of the dynamical system. In order to make the system stable, regions for the disturbance of heave motion or/and sway motion and the control parameters are numerically searched in detail. (C) 2000 Academic Press.
