| 摘 要： | 讨论高速列车会车瞬态压力波与车门模态的关系。介绍模态试验的基本理论。采用锤击脉冲激励获得单个车门的基本模态。采用正弦扫频激励获得车门 - 框架系统的衍生模态。将车门基本模态和衍生模态相结合，可了解车门弯曲和扭曲的频率与振型。通过采取措施改善车门模态参数，将减缓高速列车会车瞬态压力波的效应。

| Abstract: | 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 improv... |
