Status of development of the segmented 3 way Maglev switch and running tests

Development of the segmented Maglev switch is one of processes for the urban Maglev vehicle, which is scheduled to debut at the end of 2012 in Incheon international airport. The segmented 3 way Maglev switch is composed of 3 moving girders, 4 fixed girders, driving units, transfer units, clamping units, and articulation relieving equipment etc. In this paper, the measured results on the interaction between vehicle and switch are discussed. The measured results are following; First, consecutive moving test and natural frequency for girder and levitation rail. Second, lateral air gap of vehicle running on switching interval. Third, noise according to movement of 3 way segmented switch. Forth, thermal transformation of girder according to temperature changes. With over the measurement results, more reliability and stability of 3 way segmented switches are secured.
