2.7 Aerodynamics (Flow-induced vibration)

Growth of turbulent flow

between train and tunnel wall

Two trains coupled

Rapid growth of turbulent flow around discontinuities

such as a coupler that connects two trains and the tail of the train

The analytical results can be obtained within several days

using our high-performance computing (HPC) systems

and be applied to the design immediately.

The aerodynamic yawing moments vibrate the car bodies.

A shape that reduces aerodynamic forces gives efSET its

Superior Ride Quality.RM
