Popis: Leakage currents from DC traction power supply system of metro will reduce the lifetime of the buried pipeline. This study illustrates a real contribution in the analysis of dynamic stray current and the evaluation of the corrosion status of the buried pipeline. The metro locomotives dynamic operation process was established through traction calculation, and then analysed the dynamic influence of stray current distribution under transient finite element model. Finally, a comparison of corrosion influence of stray current is also presented. According to the simulation results, the distribution of stray current is affected by many factors, the relative position of the cathodic protection pipeline and unprotected pipeline has significant influence on stray current.
