Abstract


With the increment of the high-speed train operation speed, dynamic problems of the train-turnout system have become more obvious. This paper focus on the statistics of the measured statical and dynamical irregularity data, the dynamic responses and the influencing factors when the train passed two SC325turnouts, which is look forward to propose some useful suggests for the maintenance of the two SC325turnouts. The main work done in this paper is as follows:(1) Statistics of the maximum and standard deviation of rail gauge, track alignment and track cross level based on the measured statical and dynamical irregularity data.(2) A train-turnout time-variable system space vibration analysis model has been established and validated based on ADAMS/Rail software.(3) A dynamic simulation analysis has been conducted by using the established train-turnout model and the comparison results between the existing dynamic standards, and the calculation results indicated that the two SC325turnouts meet the requirement of the train operation safety and comfort.(4) By the dynamic simulation analysis of the established train-turnout model under various irregularity turnout conditions, the dynamic response of the train-turnout system, the maximum of the dynamic parameters and the time-history curve are obtained. It is stated that, compared with the track natural irregularity, the track geometry irregularity have a greater effect on the train-turnout system dynamic response. Moreover, the complex irregularity means stack of the vertical and horizontal geometry irregularity is the most important factor for the dynamic response of train-SC325turnout system. Furthermore, the irregularity combination condition of track profile plus gauge, track profile plus track alignment and track profile plus gauge plus track alignment are the most influential irregularity combination conditions for the dynamic response of train-SC325turnout system. (5) There are some suggests have been proposed for the maintenance of SC325turnout.
