An experimental analysis of the forces impact of a new structural design of a three-axle railway bogie to a track

The article describes the analysis of the impact of a three-axle bogie ELH-3R installed under a platform wagon type Samms on the railway track. The computer calculation of indicators of the track impact is described when the wagon moves along tangent and curved track sections with radii of 430 and 650 meters. While doing that, the cases of the movement of the platform wagon in an empty and fully loaded state were considered. The simulation was carried out at different motion speeds depending on the investigated track on sand or gravel ballast. Based on the calculation results, an assessment of the compliance of the indicators of the three-axle bogie impact on the track with the requirements of the corresponding standards was made.
