The Air Tightness Test Method of the High Speed Train
The tightness of interior space in condition of a high speed train with its side door, side window closed called train air-tightness. The paper introduces the air tightness of the high speed train and the basic methods for air tightness testing. It also applies a constant pressure leak model to test and points out that the importance of air tightness for high speed train.
