Method of Train Vertical Impulse Detection and Grade Assessment Based on Virtual Instrument

This research introduced a method based on virtual instrument,which achieved the real time detection and assessment of train vertical impulse.It analysed and processed the signal with the data processing functions,such as Correlate and ToPolar1D in the LabVIEW and LabWindows.This method could detach impulse acceleration from vibration acceleration,which gave the grade of impulse,and established a more scientific assessment standard of train vertical impulse.
