Abstract

This paper presents a passive suspension designed to stabilize a magnetically-levitated vehicle, using both vertical and lateral suspension elements. The two-mass system is broken up into six subsystems, one for each degree of freedom, assumed to be independent. The suspension design is seen to be an attempt to obtain satisfactory dynamics for several subsystems simultaneously. Steady-state constraints are shown to be in conflict with optimal dynamical behavior. Response to disturbances due to guideway roughness and wind are considered, and it is shown that the suspension can attain, although marginally, satisfactory performance.
