沈大线旅客列车构架振动测试研究

The Measurement and Analysis of Vibrational Charateristics for the Frame of Passenger Vehicles on SHEN DAO Main Railway

本文根据沈大线旅客列车构架振动测试资料对其振动特性进行了研究，得出了构架振动特性与其行车速度的一系列关系，为分析列车－轨道、列车－桥梁振动系统提供了一些重要的参数．

Frame vibration for the passenger vehicles on Shen Dao main railway are measured and analysed. By analysis, the relations between the vibrational characteristics of the vehicle frame and the train velocity are established. The information is important for studying the vibration of train railway system and train bridge system.
