ABSTRACTA load moving on sea ice, whether the weight of a vehicle or the pressure exerted by a low-flying aircraft, produces a deflection which can in extreme cases cause ice failure. The magnitude and shape of the deflection profile depends on the weight and speed of the vehicle) and also the the ice thickness and properties, with flexuralgraviry ...

Experiments Involving Moving Loads
1996There have been various experiments to investigate the effects of loads moving across floating ice sheets. In chronological order, field experiments reported in the open literature are due to Wilson (1955, 1958), Anderson (1958a), Sunberg-Falkenmark (1963), Eyre (1977), Goodman and Holdsworth (1978), Takizawa (1978), Kubo (1980), Beltaos (1981), Davys (

Moving Loads Identification Through Regularization
Journal of Engineering Mechanics, 2002This paper presents a time domain method to identify moving loads on a continuous beam from the measured structural vibration response. The method gives very accurate solutions for the forces with an improved formulation over existing methods for more efficient computation. A regularization technique is used to provide bounds on the solution. Numerical

Moving-Loads-Induced Instability in Stepped Tubes
Journal of Vibration and Control, 2004In this paper we investigate the dynamic stability and response of stepped tubes subjected to a stream of moving objects. The equations of motion for the transverse vibrations of the tube are developed using a Hamilton's principle that accounts for the out-release energy of the moving objects.

Moving Loads on an Elastic Plate Strip
Journal of Applied Mechanics, 1974The response of an infinite plate strip under an arbitrarily distributed transverse moving line load is determined. The line of application of the load is perpendicular to the infinite edges, and the load is assumed to propagate parallel to the infinite edges of the plate at constant speed.

Differential Quadrature Analysis of Moving Load Problems
Advances in Applied Mathematics and Mechanics, 2016AbstractThe differential quadrature method (DQM) has been successfully used in a variety of fields. Similar to the conventional point discrete methods such as the collocation method and finite difference method, however, the DQM has some difficulty in dealing with singular functions like the Dirac-delta function.

An investigation of the dynamic load effects of moving loads on beams may be required in cases of heavy vehicles or a train passing a flexible bridge, though the problem may not necessarily be that of the bridge, it may also involve uncomfortable vertical oscillations of the vehicle. The problem may also occur on moving hoisting forces on heavy cranes.

Marine Technology and SNAME News, 1976
Over the years, a number of unique load-moving systems have been developed in response to needs in heavy fabrication programs. The systems are designed principally to improve construction techniques in a new or expanding fabrication facility. All systems are focused on low capital investment, making them particularly adaptable to short-term projects ...

For large-span bridges the problem of the effects of a moving continuous load is of equal — if not greater — importance than the problem of a moving concentrated force. It has been treated at length by several authors, 1.1. Gol’denblat [97] and V. V. Bolotin [20] among them.
