In the mid-low speed Maglev train, levitation force produced by end electromagnets is influenced train due to eddy current effect, especially front-end at high speed. this paper, effect of calculated an analytical method, which validated Finite Element method (FEM). To compensate a decrease force, two improved structures electromagnet modules are designed and compared. One permanent magnet comp...

The suspension system of the EMS (Electro-Magnetic Suspension) medium-and-low-speed maglev train is affected by eddy current effect when in motion. This a crucial problem related to improvement operation speed. In this article, phenomenon analyzed and method suppressing put forward. Firstly, theoretical analysis experimental verification are carried out. It worth mentioning that data, which tho...

Auxiliary stopping area (ASA) is the necessary emergency facility for train safety of normal high-speed maglev. The study addresses ASA layout problem maglev operated bidirectionally on single track. First, an optimization model unidirectional double-track lines considering safety, operation efficiency, and construction cost established, two basic methods are investigated based distance demand ...

The high-speed maglev train will be subjected to extremely obvious aerodynamic load and instantaneous impact during passing another train, which brings significant challenges the train’s suspension stability safe operation. It’s necessary consider influence of shock waves in design control algorithms. Traditional proportion integration differentiation (PID) cannot follow change vehicle paramete...

As a new mode of transportation, maglev train has broad prospect. one the key technologies train, suspension control technology been hot research field. Maglev characteristics complex system modeling, strong nonlinear model, unstable open-loop system, and changeable working conditions. To date, widely used method is still design PID controller based on linearized model. However, with passage ti...

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. It is installed on board and is used as the feedback end. Restricted by the maglev train's structure, the permanent magnet electrodynamic suspension ...

This paper mainly researches one method of speed and location detection for maglev vehicles. As the maglev train doesn't have any physical contact with the rails, it has to use non-contact measuring methods. The technology based on the inductive loop-cable could fulfill the requirement by using an on-board antenna which could detect the alternating magnetic field produced by the loop-cable on r...
