Research on Acquisition System for Vertical Vibration Characteristics of CWR Track based on LabVIEW
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 its feasible to predict the temperature stress of a CWR track by testing its vertical vibration frequency. A frequency acquisition program based on the LabVIEW is presented at last
