A STUDY ON DYNAMIC INTERACTION ANALYSIS FOR MAGLEV VEHICLE AND GUIDEWAY STRUCTURES

MagneMotion Maglev Demonstration on ODU Guideway

MagneMotion and Old Dominion University undertook a cooperative agreement to demonstrate the MagneMotion M3 urban maglev technology on an existing elevated guideway on the ODU campus in Norfolk VA. M3 was designed for urban applications with speeds up to 100 mph, acceleration up to 1.6 m/s2, and a 60 foot turn radius. Figure 1 shows the “sled” vehicle on the ODU guideway. This vehicle was weigh...

Dynamic response analysis of single-span guideway caused by high speed maglev train

High speed maglev is one of the most important reformations in the ground transportation systems because of its no physical contact nature. This paper intends to study the dynamic response of the single-span guideway induced by moving maglev train. The dynamic model of the maglev train-guideway system is established. In this model, a maglev train consists of three vehicles and each vehicle is r...

Hopf Bifurcation of Maglev System with Coupled Elastic Guideway

In this paper, the dynamical behavior of single magnet suspension system of maglev train considering the elastic guide-way is researched through HOPF bifurcation theory. With three states feedback variables (gap, current, velocity), the HOPF bifurcation conditions and corresponding vibration frequency of the coupled system is presented under different flexible guideway conditions, that is, the ...

Restrain the Effects of Vehicle-guideway Dynamic Interaction: Bandstop Filter Method

To restrain the effects of vehicle-guideway dynamic interaction, a bandstop filter is introduced into the maglev levitation controller. To compensate these phase-lags in some particular band produced by the bandstop filter, an allpass filter is designed, which can not only attenuate the amplitude at the resonance frequency, but also decrease the phase-lag in relative-wide band. The simulation r...
