The thermal energy is the result of dissipation caused by aerodynamic drag, mechanical resistances, and inefficiencies in the power unit. In this paper, heating of aerodynamic drag are calculated in terms of pressure drag and friction resistance as well. Heating of auxiliary equipment, train equipment, train braking and pantograph electric arc etc. has also been comprehensively considered, and the energy loss of heat conduction induced by tunnel wall has been taken into account. As a result, the temperature rising in the long tunnel is generated and the result can provide us with a useful reference for design of the long tunnel for the high-speed train and its traction capacity.Index TermsAvailable to subscribers and IEEE members.ReferencesAvailable to subscribers and IEEE members.Citing DocumentsAvailable to subscribers and IEEE members. |
