Rail-wheel Interaction and Its Influence on Rail and Wheels Wear

Procedia Manufacturing, 2019
Abstract Railway superstructure and the rolling stock form a complex mechanical system. Due to the interaction between the rolling stock and the rail, wears occur, both at the wheel profile, as on the rail. This wears generate interaction forces that accelerates the railway track deterioration.

Affordable and Clean Energy: CO2 Emissions, Resilience and Inequality

Sustainable Development, EarlyView.
ABSTRACT Sustainable development means building the resilience of both people and the planet. It includes implementing strategies which reduce emissions while also enabling more vulnerable households to transition to clean and affordable energy. This paper examines household CO2 emissions in Ireland to highlight those who emit most and least in key ...

An Accurate and Fast Method to Inspect Rail Wear Based on Revised Global Registration

IEEE Access, 2018
Rail wear inspection is vitally important in the railway industry. Conventional methods mainly use manual or static measurements to detect rail wear, which are inefficient, imprecise, and unreliable.

Carbody sway behaviour of railway vehicles due to track irregularity from rail alternate side wear

Railway Engineering Science
Track irregularity from rail alternate side wear is manifested as uneven rail wear waveforms alternating in the left and right rails with equal intervals, which will cause carbody sway behaviour of railway vehicles and greatly influences the passenger ...

Insights Into Paint‐Bake Toughening of Resistance Spot Welds of a 2.0 GPa Warm‐Stamped Medium‐Mn Steel

steel research international, EarlyView.
Paint baking of resistance spot welded joints of 2.0 GPa warm‐stamped medium‐Mn steel activates low‐temperature tempering, forming fine cementite in the fusion zone and enhancing toughness. Crack propagation resistance increases, shifting the failure mode from partial interfacial to complete pullout, with peak load and energy absorption rising ...

The wear resistance research of the rail contact surface depending on the grinding process

Mechanics and Advanced Technologies, 2019
Background. Continuous mechanical loads on the rails during its contact with the wheel lead to an accumulation of residual stresses in the surface layers of the rails, resulting in fast-growing fatigue cracks.
