Dynamic Interaction of High Speed Maglev Train on Girders and Its Comparison With the Case in Ordinary High Speed Railwys

Reviewing the achievements in vertical, lateral and longitudinal dynamics of high speed train, the dynamic interaction between the high speed maglev and girders has been studied.A comparison of it with the case in wheel/rail typed high speed trains was discussed in detail.The main conclusion obtained is that around 300 km/h wheel/rail trains should be the backbone of the ground high speed rail transit system.In the case that the extraordinary high speed, e.g.400~600 km/h, is required, then the maglev is feasible.The maglev serves as a kind of complement of the main high speed rail system.From this point of view, the high speed maglev Pudong Airport Transit Line in Shanghai is important and should be well constructed.But to construct Beijing Shanghai wheel/rail high speed railway is even more important, and should be put into action as soon as possible.
