As one of the important core components train running parts, wheel rail related force will directly affect vehicle performance and passenger comfort. Take a high-speed as research object, track coupling dynamic model is established. The influence polygon on vibration characteristics bogie system analyzed through simulation. results show that when wear occurs, effective value lateral acceleratio...

This study addresses the Hyperloop characterized by a capsule-type vehicle, superconducting electrodynamic suspension (SC-EDS) levitation, and driving in near-vacuum tube. Because is different from conventional transportation, various considerations are required vehicle-design stage. Particularly, pre-investigation of vehicle dynamic characteristics essential because close relationship among de...

Abstract Fault detection and isolation of high-speed train suspension systems is critical importance to guarantee running safety. Firstly, the existing methods concerning fault or are briefly reviewed divided into two categories, i.e., model-based data-driven approaches. The advantages disadvantages these categories approaches summarized. Secondly, a 1D convolution network-based diagnostic meth...

High-speed trains serving in a crosswind region are bearing more significant safety risks. Based on the three-dimensional (3D) Unsteady Reynolds-Averaged Navier–Stokes (URANS) turbulence model, Computational Fluid Dynamics (CFD) computational work was conducted present study to predict transient aerodynamic load of train. The then employed as input dynamic system perform analysis running safety...
