摘要

随着铁路交通建设的快速发展，铁路交通运行引起的环境振动日益引起人们的关注。为了更好地研究地面振动荷载的特性及其传播规律，根据列车本身的结构和道床结构特性，将钢轨、轨枕、道床以及高出地面部分的路基作为整体，建立车厢-转向架-道床结构体的地面振动荷载二系弹簧计算模型，通过分析现场测试得到的地面振动速度数据和车辆自身的振动情况，并利用傅立叶变换程序FFT对地面振动荷载数据进行傅立叶变换，得到地面振动荷载的数定表达式。

Abstract

With the rapid development of the construction of rail transport

the vibration caused by the operation of rail transport is causing an increasingly concern. In order to study the characteristics of ground vibration load and its law of propagation

we set the rails

sleepers

ballast bed and roadbed above the ground as a whole according to the structure of the train and characteristics of the structure of ballast bed

and build a two-line spring model consisting of a car-bogies-ballast bed structures to calculate the ground vibration load. By analyzing the test data about the velocity of ground vibration and the vibration of the train itself

we can get the number expressions of the ground vibration load by using fast Fourier transform (FFT) program to analyze the ground vibration load data for Fourier transform.
