Strength Evaluation of a Bogie Frame by Different Methods

Mechanical Engineering Science, 2019
Some crucial loads that current strength design specifications have not taken into account are also considered when assessing the strength of a bogie frame. Calculation methods of these loads come from load analysis. Finite element simulation and fatigue test rig have been used to assess static strength and fatigue strength of a bogie frame.

Integrated Traction and Guidance Control of Independently Rotating Wheelsets in Urban Rail Vehicles Using Flux‐Map‐Based Torque Reference Generation

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Independently rotating wheelsets require accurate realization of traction and differential wheel torques under electrical constraints. This paper proposes a hierarchical control framework combining speed PI and LQ‐servo lateral guidance with scaling‐based torque allocation and a flux‐map current reference generator that accounts for DC‐link voltage ...

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,
