Abstract: The maximum economic speed is hard to exceed 400 km/h when high-speed trains run in the atmosphere. ETT (Evacuated Tube Transportation) will be the perfect fast vehicle on land. Taking high speed train set as a model, using Pro/E, the parameterized model of ETT was established. Analyzing the train actual boundary condition, based on FLUENT software and the turbulence model, considering multi - field coupling condition which involved the outer flow field, the aerodynamic drag field and velocity field, the numerical simulation and computation was finished. Furthermore, the laws of many parameters affect air - resistance and aero - lift were researched. By use of fuzzy multi - criteria evaluation model, the main parameters of system were optimized. The works can provide the feasibility basis for ETT.

 

Keywords: ETT, Aerodynamics, Multi-field coupling, Optimization design.
