This paper investigates the failure mechanisms and residual life of coupler yokes through
material characterization and chemical composition analysis. Initially, comprehensive …

A simulation procedure to predict the probability of rail break due to a measured wheel load
spectrum is presented. The load distribution includes a representative proportion of high …

Flats and polygonization are common forms of out-of-round wear for railway wheels. To
investigate the relationship between wheel flats and polygonal wear in high-speed trains …

总结了近几年国内外轨道交通列车车轮多边形的研究成果, 分析了导致车轮形成多边形的主要
因素与发生机理以及动车组与地铁车辆多发的高阶车轮多边形不同的原因, 探讨了车轮多边形的 …

Fatigue failure behavior of U75V rail material under Ⅰ+ Ⅱ mixed-mode loading is analyzed
and characterized in this work. A fatigue crack propagation experiment was carried out on …

In the railway systems, induced contact between wheels and rails creates maximum shear
stress around the contact surfaces. These shear stresses vary with the wheel's rolling and …

As critical load-bearing components of high-speed trains, the design and evaluation of axles
primarily adhere to the principle of infinite life, supplemented by systematic flaw detection to …

Hollow axles are critical safety components for high‐speed trains, and the operational safety
of the axle is ensured by combining infinite life design and damage tolerance analysis …

With the development of urbanization, subway vehicles often operate on dedicated tracks,
and the wheels experience wear characteristics that correspond to the track conditions …
