Research on Tracking Interval Time of High Speed EMU Based on Tracking Arrival Model

This paper makes a detailed analysis of the picking up operation process for the high-speed EMU, a tracking arrival model for the EMU is established, the arrival interval time Tarrive calculation formula of station is revised, the tracking arrival process of multiple EMU is simulated by using the MATLAB software, and the impact of it on the picking up efficiency is explored by changing the section tracking interval time Ttrack. Combined with the ATP curve design algorithm and the EMU braking distance calculation theory, the calculation method of the braking distance under ATP curve monitoring is studied. The Ttrack and Tarrive of the CRH2 and CRH3 type EMU under the different line conditions are checked and calculated respectively, the key factors affecting the tracking interval time are analyzed according to the results, and the reasonable suggestions are put forward on how to compress the tracking interval time of high-speed railway and improve the operation efficiency of line.
