Introduction of Magnetically levitated (MAGLEV) vehicles in urban ground transportation offers various challenges in design and control of the vehicle and guideway parameters. The research output in this field is increasing day by day; however, there is still the necessity of finding simpler and cost-effective analysis that can be adopted in Cited by: 1. The prototype machine was designed using FEM magnetic analysis. According to this analysis, the device had sufficient magnetic force to control the rotor within a designed airgap. In addition, axial directional dynamic characteristics were measured.

This article, which reviews various aspects of the dynamic characteristics, experiments and analysis, and design guidelines for maglev systems, discusses electrodynamic system (EDS) maglev vehicle stability, motion-dependent magnetic force components, guideway characteristics, vehicle/guideway interaction, ride quality, suspension control laws Cited by: This paper explains the basis features of a Magnetically Levitated Vehicle, which consider the magnetic suspensions, propulsion and guidance. There are basically two modes of magnetic suspension, utilizing either the repulsive force between vehicle-borne superconductive magnets.
The design and development of these transportation systems needs considerations of suspensions, propulsion, power pick up and guideway construction. A typical suspension consists of a primary suspension which contacts the road and a secondary suspension which connects the vehicle body to the primary suspension. The dynamic responses of a magnetically levitated vehicle (maglev) in a crosswind are studied because the action of the wind field is one of the main factors affecting the stability and safety of the maglev at high speeds. First, a model of the maglev system is established to represent four vehicle motions: heave, sway, pitch and roll. The inductive reaction sphere (RS) brings the benefit of simple, economical, and miniaturized design, and it is capable of multi-DOF torque generation. Thus, it is a suitable choice for the angular momentum exchange actuator in attitude control of micro-spacecrafts. To synthesize symmetric distribution of eddy currents and improve the speed and stability of rotation, a novel Cited by: 2. Practical Applications of Magnetic Levitation Technology, Final Report 7 In order to design a suitable controller for the maglev system, the sub-system components must be modeled or characterized. The sensor sub-system is modeled by measuring its voltage output as a light shieldFile Size: 3MB.
The analytical and numerical models can be used for the design of large planar actuators, for the fast comparison of actuator topologies, and in the decoupling and commutation algorithm.
