Experiment Verification of Distribution Characteristics of Stray Current in Urban Rail Transit

At present, research on the distribution of stray current mainly focuses on its static distribution, but there is less research on the dynamic distribution. Aiming this problem, a mathematical analytical model with a structure of running rail-drainage network-ground is proposed, and an experimental platform is built based on the analytical model for verification. Finally, a simulation model is established for comparison. The research results indicate that the experimental and simulation has the same trend, and the experimental design is correct and feasible.
