The relation between train door’s modes and transient pressure wave for high-speed train’s crossing is discussed. The basic theory on mode test is introduced. The basic mode of a single train’s door was obtained by hammering-impulse excitation. The developing mode of train’s door-frame system was obtained by sinusoidal frequency-scanning excitation. Combining the basic mode and the developing mode of the train’s door, its frequencies and modes of bending and torsional vibrations can be understood. With the improvement of the mode’s parameters of the train’s door, the effect of transient pressure wave in the high-speed train’s crossing can be reduced and relaxed.
