        摘要：Due to the increasing speed of the locomotive, the pantograph-catenary disconnection was getting worse, and the pantograph arc occured frequently. The pantograph arc etched the pantograph slider and contact wire, and the etching level was influenced by arcing energy. In this paper, the arc voltage and current of different traction current and power factor was measured by pantograph-catenary arcing test system. The relationship between average arcing duration and traction current, power factor of load was analyzed, as well as the arc energy affected by power factor of load was studied. The results showed that the average arcing duration becomes longer in index with traction current increasing; the arcing duration with inductive load is longer than with resistive load; the arc energy decreases with the rising of load power factor.

        摘要：A spline-connecting anti-roll torsion bar was simulated by ABAQUS software, which was shown being correct and reliable by comparing the results with the experiment. With using of sub-model, the local stress distribution of the spline was obtained.The results indicated that simplifying the contact relation of the entirety model could reduce the computational cost and increase analysis efficiency, and the sub-model solution solved the problems of too much grid need to calculate, long calculate time and the poor convergence. The accurate stress results provided strong support for the fatigue analysis and the extraction of the fatigue failure mode of the torsion bar system.

        摘要：With signal and noise state model of Kalman filter, the frequency was unbiasedly estimated, which was suitable for accurate measurement of locomotive speed. Time-varying window was used to capture pulse signals to overcome shortcomings of conventional algorithm such as instable refresh time and measurement accuracy, as well as to ensure the accurate measurement of different frequencies. FPGA-based algorithm design and simulation has demonstrated that with Kalman filter and time-varying window, it was effective and accurate to measure locomotive rotate speed.

        摘要：Based on calculation and analysis, the conditions of wheel keeping from sliding in brake, selection of freight train brake rating, and relations between train axle, the highest running speed, distance limit of emergency brake, and brake rating were expounded. It was pointed that the train highest running speed must be reduced when the axle load was increased to 25~30 t without extending brake distance limit, on the other hand, the train brake distance limit must be extending to keep the highest running speed.
