The response of ice cover to a load moving along a frozen channel [PDF]

open access: yes, 2016
Deflections and stresses in an ice cover of a frozen channel caused by a load moving with a constant speed along the channel are studied. The channel is of rectangular cross section. The ice cover is isotropic and clamped to the walls of the channel. The

Online adaptive semi-active vibration damping of slender structures subject to moving loads

open access: yesMATEC Web of Conferences, 2018
The paper deals with the adaptive optimal semi-active control of the slender vibrating structures subjected to the moving loads. The deflection of the structure is governed by Euler-Bernoulli beam equation approximated by the system of bilinear ordinary ...

Deflection of broken ice caused by an external load moving along a channel

open access: yesJournal of Physics, Conference Series, 2020
The unsteady problem of a load moving along a channel covered with broken ice is considered. Deflection of the broken ice is described by the equation of flotating liquid. The channel has a rectangular cross-section.

Analysis of Technical and Energy Indicators of a Multi-Motor Electric Drive for Urban Public Transport [PDF]

open access: yesProblems of the Regional Energetics, 2019
The aim of this article was to analyze the profitability of using a multi-motor electric drive instead of a single-motor electric drive in a city vehicle to ensure the reduction of the electrical energy losses.

An Axially Compressed Moving Nanobeam Based on the Nonlocal Couple Stress Theory and the Thermoelastic DPL Model

open access: yesMathematics, 2023
This article introduces a new model that can be used to describe elastic thermal vibrations caused by changes in temperature in elastic nanobeams in response to transverse external excitations.

Exact closed-form solutions for Lamb’s problem—II: a moving point load [PDF]

open access: yesGeophysical Journal International, 2020
In this paper, we report on an exact closed-form solution for the displacement in an elastic homogeneous half-space elicited by a downward vertical point source moving with constant velocity over the surface of the medium.

Dynamic response of periodic infinite structure to arbitrary moving load based on the Finite Element Method

open access: yesProceedings of the YIC 2021 - VI ECCOMAS Young Investigators Conference, 2021
Dynamics of repetitive structures subjected to moving loads is a common problem in railway engineering. Bridges, rails or catenaries are the most representative periodic structures, on which the train acts as a moving excitation.

New approach to analysis of railway track dynamics – Rail head vibrations

open access: yesOpen Engineering, 2021
The article presents an original approach to the analysis of railway track dynamics. The “beam-inside-beam” concept is introduced as a dynamic generalisation of the static head-on-web effect, based on the two-layer model of rail.
