Numerical Analysis for Dynamic Instability of Electrodynamic Maglev Systems
Shock and Vibration, 1995 Suspension instabilities in an electrodynamic maglev system with three- and five-degrees-of-freedom DOF vehicles traveling on a double L-shaped set of guideway conductors were investigated with various experimentally measured magnetic force data ...

Modeling of Electrodynamic Suspension Systems [PDF]
Volume 2: 30th Annual Mechanisms and Robotics Conference, Parts A and B, 2006 Characteristics of magnetic–levitation system are studied using dynamic models that include motion–dependent lift, drag, slip, and roll motions. In addition, the contact constraint between the vehicle and the track is modeled using the penalty method. Unknown numerical parameters are identified using the optimization technique.

Summary of a Bearingless Motor with Passive Electrodynamic Axial Suspension [PDF]
, 2021 Either active control or passive stabilization can be used to achieve non-contact magnetic sus-pension in magnetic bearings and bearingless motors. As the rotational speed is increased, the d-axis current becomes harder to regulate, thus motivating the ...

Research on the Filtering Algorithm in Speed and Position Detection of Maglev Trains
Sensors, 2011 This paper introduces in brief the traction system of a permanent magnet electrodynamic suspension (EDS) train. The synchronous traction mode based on long stators and track cable is described. A speed and position detection system is recommended.

Modeling and control of a simplified high-speed vehicle moving in reduced-pressure conditions [PDF]
Archive of Mechanical Engineering, 2019 In times of rapidly progressing globalization, the possibility of fast long-distance travel between high traffic cities has become an extremely important issue. Currently, available transportation systems have numerous limitations, therefore, the idea of

Equivalent model of the side wall electrodynamic suspension system
Electrical Engineering in Japan, 1997 The side wall electrodynamic suspension (EDS) system has the advantage of not requiring gap control, and the magnetic drag is smaller than for the repulsion arrangement. This levitation system is applied in the JR magnetically levitated (Maglev) transportation system.

Active and Regenerative Control of an Electrodynamic-Type Suspension.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996 An active vibration damper and an isolator are capable of reducing vibration remarkably and adaptively. One of their disadvantages is that they require a large amount of energy. Since vibration is a type of energy, a question arises as to how we can utilize this energy.

Longitudinal vibrations in electrodynamics suspension system
Transportation systems and technology, 2016 A system of electrodynamics suspension (EDS) in which the primary source of the field (electromagnet) is moving in a straight line parallel to the surface of the track and his speed makes small oscillations around a mean value is considered. The approximation of an infinitely wide track is allowed, the primary source of the electromagnetic field acts ...
