Numerical analyses of dynamic stability of maglev vehicles in crosswind field

Shi Xiao-hong

Abstract

The model of maglev control system,which represents five kinds of vehicle motions such as heave, sway,pitch,roll and yaw,was established.Based on the steady and incompressible Navier-Stokes equation and K-eturbulent model,numerical calculations for the aerodynamic characteristics of vehicle/guideway system under crosswinds were done with the use of the finite element analysis software ANSYS.The dynamical characteristics of the vehicle were studied.The analysis result showed that wind velocity,vehicle velocity and control parameters have significant influences on the stability of maglev vehicles and their regularities were given out.
