文章按七种不同的车辆模型计算了列车分别以五种不同的速度过桥时桥梁的空间动力响应以及列车在桥上不同位置时车-桥系统的自振频率和振型。
Seven kinds of different vehicle models are used to calculate the space dynamic responses of the bridge on which a train moves at five different speeds.
为避免桥梁共振，设计时应满足第一阶竖向自振频率大于车辆最大速度与车辆长度的比值。
To avoid the most dangerous resonance, the first vertical frequency of the bridge should be greater than the ratio of the maximum vehicle speed to the vehicle length in design.
