چکیده

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 results show that the proposed filter can restrain the vehicle-guideway vibration at the desired frequency.

Controller Design for Commercial Maglev Vehicle

An electromagnetic levitation controller design considering guideway deflection is presented. Even though to design a maglev controller to make a vehicle steady suspension under guideway deflection is a key technology in maglev vehicle system, the vehicle-guideway interaction effects haven’t well explored and yet settled. Unlike most approaches based on the linear model, a maglev controller is ...

Identification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model

In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...

Finite element analysis of vehicle-structure interactions during launching of remotely piloted air-vehicles

The problem of finite element modeling and analysis of dynamic interactions between the launcher and a remotely piloted aircraft structure is considered. The governing equations of motion are shown to constitute a set of ordinary differential equations with time varying structural matrices. An iterative strategy that treats separately the dynamics of the launcher and the aircraft is developed. ...

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...

Dynamic Response of the Coupled Vehicle-Floating Slab Track System using Finite Element Method

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...
