Fatigue strength analysis of bogie frames under random loads [PDF]
In this study, a method for analyzing the fatigue strength of a bogie frame under a random load was proposed. Based on the geometric features, a welded joint coordinate system was established to compute the stress components of each node in this coordinate system.

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 ...

Sliding‐Mode Control of Electromagnetic Suspension Systems Considering Disturbance Compensation
This study proposes an integrated control strategy for magnetic levitation systems, combining a cascaded linear extended state observer with an improved sliding‐mode control. This method accurately estimates and compensates for disturbances, significantly enhancing suspension stability and rejection capability.

To address the challenges of detecting the variable pose of bolster springs within the confined space of a bogie frame and identifying potential entrapment interactions between the springs and surrounding obstacles, this study proposes a method for identifying the trapped state of bolster springs based on heterogeneous information fusion. This approach

Carbody chattering in high‐speed electric multiple units (EMUs), induced by the coupling between bogie hunting motion and the carbody diamond‐shaped mode, severely affects ride comfort and operational safety. Real‐time monitoring of its evolution remains challenging due to the difficulty in accurately distinguishing among the nonchattering, incubation,
