- high-speed trains

German transrapid (electromagentic attraction)

Japanese MAglev (electrodynamic repulsion)

Grench TGV (wheel on rail)

Vu Quoc and Olsson 1989 CMAME

vehicle/structure interaction, where vehicle is the high speed maglev and the structure is the the flexible guideway

 

  nominal position of wheel (w/o guideway definition)

 , horizontal coordinate

  axial deformation (displacement) of guideway, where   is the time parameter

  transverse deformation (displacement) of guideway

 , where := means equal by definition (non symmetric)

NOTE:   and def are symbols (no direction)

  means A is defined by B

  means B is defined by A
