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 vehi cle with a control system moving on flexible guideways. The vehicle is simp lified as a body with the primary and the secondary suspension parts and ha s five-degree-of-freedom (d.o.f.). So, its five kinds of motions, i.e., hea ve, sway, pitch, roll, and yaw motions are considered. The numerical result s show that the dynamical characteristics of a coupling maglev vehicle/guid eway system are different from those of the uncoupling system in which the deformation of the guideways is neglected. For the coupling system, one kin d of disturbances in the five motions may excite several other kinds of mov ing responses. Both the disturbances and the control parameters have an inf luence on the stability of the dynamical system. In order to make the syste m stable, regions for the disturbance of heave motion or/and sway motion an d the control parameters are numerically searched in detail. (C) 2000 Acade mic Press.
