The Effects of Diabatic Heating on Storm Track Dynamics
… heating in Northern Hemisphere winter storm tracks are studied in the context of a nonlinear primitive equation model with vertical and horizontal resolution adequate to capture shallow, short wavelength baroclinic waves. The model is forced by realistic orography and diabatic processes …

Train-track discrete-element-method model for simulating ballasted track dynamics: coupling and validation
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-02-04 without embargo terms

Dynamic analysis of a tracked snowplowing vehicle and assessment of ride quality
Tracked snowplow vehicles, designed for removing snow from the sidewalks, pose severe ride environment for the drivers, primarily arising from road wheel-track-terrain interactions. The drivers of such vehicles are thus exposed to a comprehensive magnitude of low frequency whole-body vibrations. …

The development of rail-head acoustic roughness
… of rail-head acoustic roughness on tangent track has been formulated. The model consists of a two-dimensional time domain wheel-rail interaction force calculation, with the normal force used as the input to a two-dimensional rolling contact and wear model. The possibility of multiple wear …

Discrete element modeling of railroad ballast using imaging based aggregate morphology characterization
Ballast is an essential layer of the railroad track structure, and provides primarily drainage and load distribution. In general, ballast aggregates are considered as uniformly graded, angular shaped with crushed faces. However, various ballast aggregate gradations and particle shapes are in use …

Nonlinear vibration of beams and plates resting on elastic foundations having nonlinear stiffness properties
… railroads, airports, highways, and railway tracks. For example, when studying railway track behaviour, a beam on an elastic foundation (BoEF) theory is often employed, and the study can be extended to track dynamics, noise, and vibration. Winkler (1867) was the first to introduce the topic …
