In each span, analyze and list the maximum value, average value and minimum value of contact force of pantograph network; maximum value of hard point and shock; maximum dynamic height, minimum dynamic height of contact wire and dynamic height difference within a span. To master the entire testing speed levels and the current receiving performance of pantograph network of the entire testing region, the report provides pressure scatter diagram in speed level and the pressure curve of the entire process under the typical testing speed and the hard point scatter diagram.
