摘要
本文对实测的钢轨接头处轨道结构加速度进行了谱分析，给出了钢轨、轨枕、道床的加速度功率谱，从频域分析了接头冲击响应的特性，对接头冲击的隔离和减振提供了依据。
This paper studies the properties of the wheel /rail joint impact,and makes a spectral analysis of the impact response tested in the actual structure,The acceleration powerspectral of the rail,tie and ballast are given,The paper analyzes also the characteristics of thetrack structure impacting response by means of frequency,and provides the basis for the reduction and absorption of the vibration.
