| Abstract: | Referring to the feature of the data processing for the measured dynamic stresses of railway vehicle system, a data analysis system was developed to deal with the processing of the vehicle dynamic stresses. The structure of the system was studied on the basis of software engineering. The software was realized according to the rainflow cycle counting algorithm which has the merit of fast and reliable dealing with large ammout of data flow. The software has a friendly, open and easily removable interface and is valuable for practical use. |
