从新干线收集到的振动数据认为,虽然尾车和头车的振动情况几乎完全一样,但尾车的振幅比其他车辆要大。为了分析这种原因,我们调查了尾车的大振动是否来自整列列车的蛇行振动特性;计算了车体蛇行运动的稳定性和振动模式;为了评定轨道不平顺的振动响应如何反映蛇行振动特性,又计算了整列列车的振动响应。结果表明尾车振动大的一个原因就是由于整列列车蛇行运动的振动模式。
The vibration data collected from the Shinkansen think that although the vibration of the tail car and the head car is almost the same, the tail car has a larger amplitude than other vehicles. In order to analyze this reason, we investigated whether the large vibration of the tail car comes from the meandering vibration characteristics of the whole train. The stability and vibration mode of the car body’s meandering behavior are calculated. In order to evaluate how the vibration response of the erratic vibration reflects the vibration characteristics, Also calculated the entire train vibration response. The result shows that one of the reasons that the tail car vibrates greatly is that it is due to the vibration mode of the entire train.
