摘要:
为研究不同频谱特性的地震作用对高速列车振动的影响,本文建立31自由度的机车模型,利用三角级数法生成轨道不平顺。 通过在水平、竖直两个方向输入不同频谱特性的三条地震波,主要从频域角度分析总结了不同车速和不同地震峰值加速度下车体的垂直和横向加速度。结果表明,地震对车体横向振动的影响大于垂向; 地震动的低频成分居多时,会使得车体振动响应增大。地震峰值加速度对车体振动有较大影响且车速和地震峰值加速度共同控制车体的横向和垂向振动主频。列车运行时,若遇到卓越频率低且峰值加速度较大的地震激励,会对车体的振动用有较大的影响
Abstract:
In order to research the effect of seismic action with different spectral characteristics on the vibration of high-speed trains, a 31 degree of freedom vehicle model is established in this paper and the trigonometric series method is used to generate the track irregularities. Through inputting three seismic waves with different characteristic in horizontal and vertical directions, the vertical and lateral accelerations of the vehicle body at different vehicle speeds and different peak accelerations are analyzed and summarized from the frequency domain perspective. The result indicated that the effect of seismic on lateral acceleration of vehicle body is larger than vertical, when seismic wave is including more lower frequency will lead to vehicle body vibration response increased. The peak acceleration of the earthquake has a great influence on the vibration of the vehicle body and the vehicle speed and the peak acceleration of the earthquake jointly control the main frequencies of the lateral and vertical vibrations of the vehicle body.
