Maglev Freight Conveyor Systems
Published in Petros A. Ioannou, Intelligent Freight Transportation, 2008
Maglev is not a new concept. After several years of development, the world’s first commercial urban Maglev and high-speed Maglev passenger lines have gone into service in Japan and China, respectively. Application of Maglev technology to a freight-only system is an innovative alternative to conventional road or rail infrastructure. The environmental and community constraints on expanding conventional means of container transport through the Los Angeles basin indicated as early as 2002 that a Maglev freight system had costs comparable to highway and rail for moving containers through urban areas.9 The referenced study involved an electromagnetic suspension (EMS) design by Transrapid, the German developer of the world’s first commercial Maglev system. Recent work at Lawrence Livermore Laboratory and General Atomics (GA) has shown that an electrodynamic suspension (EDS) Maglev also has significant potential benefits for transporting containers.

The superconducting electrodynamic suspension (EDS) train is one of the magnetic levitation trains and is the only ground transportation tool achieving a manned speed of more than 600 km/h [1]. Dynamic performance is the key to determine the safety and stability of the superconducting EDS train. In the early stage, Japan lacked theoretical research on the dynamic performance of superconducting EDS train, and the test cars developed generally had problems with vibration and ride comfort [2]. Furthermore, the safety, stability and stationarity of train operation will be greatly affected by the high speed operating conditions due to its lightweight car body. Therefore, the vibration reduction control is essential to ensure the running performance during the high-speed operation of the EDS train [3–5].
