RETRACTED: Research on Acquisition System for Vertical Vibration Characteristics of CWR Track based on Lab VIEW (Retracted Article)

This paper presents a dynamic model for analysing the vertical vibration response characteristics of continuous welded rail (CWR) track under longitudinal temperature stress, and reveals that the parameters in the model, such as the wear of the rail, rail types, the sleeper unsupported spacing, have great influences on the relationship between the track vertical vibration characteristics and the longitudinal temperature stress. The datas of analysis and in-field measurements are compared, whose results identified that it's feasible to predict the temperature stress of a CWR track by testing it's vertical vibration frequency. A frequency acquisition program based on the Lab VIEW is presented at last.
