Dynamic Modelling of the Aerodynamic Characteristics of a 600km/h High-Speed Magnetic Levitation Train Traversing a Tunnel

This paper adopts the unique dynamic model test system for aerodynamic characteristics of high-speed magnetic levitation trains with speeds of 600 km/h and above of Central South University to carry out dynamic model test and research on eight different head types of high-speed magnetic levitation trains in open line operation, rendezvous, single-car passing through tunnels and rendezvous in tunnels, etc., and to obtain and analyse the resistance of different head types of trains in open line operation, the wind of the train, the characteristics of the rendezvous pressure wave, the pressure wave propagation law of the surface of the train and the surface of the tunnel when the train passes through the tunnel, as well as to analyse the microair pressure wave propagation characteristics of the train caused by a single-car passing through the tunnel.When the train surface and the tunnel surface pressure wave propagation law, and analysed the train single car through the tunnel caused by the micro-barometric pressure wave propagation characteristics, for high-speed magnetic levitation train design and operation to provide a scientific basis.
