Research on Strength Test Technology of Bogie Frames
IOP Conference Series: Earth and Environmental Science, 2020 Abstract The bogie frames play a vital role in the reliable operation of rolling stocks. In order to more effectively test the performance of the bogie frames’ strength, a test plan of bogie frames’ static tests and fatigue tests is designed according to related standards which is carried out by calculating the load and applying the load

A 3D Visual Detection Model for Bogie Pose of Maintenance Robot Based on Deep Learning
Journal of Robotics, Volume 2026, Issue 1, 2026.The bogie of freight railcars is a critical component affecting train safety and maintenance automation. Traditional pose localization and bolster tilt detection methods rely heavily on manual measurements and laser ranging, which suffer from high environmental sensitivity, limited accuracy, and poor real‐time performance. To address these limitations,
