“…The collaboration of the rolling stock and the rail track is simulated as well, this determines the features of their mechanical interaction [6,7] while carriage passing of the butt, including shock interaction. Current studies indicate that the interaction between rolling stock and railway track components define the parameters of durability in operation, the strength and rigidity of the track [14,15,21,29]. One of the essential components of such interaction is shock interaction.…”

Mechanical and mathematical models of mechanical multidimensional discrete-continuous systems "carriagetrack" in terms of static and impact interaction in a butt roughness zone are proposed. Their interaction is investigated with the example of a four-axle car and a track for four motion phases in the place of isolated butt roughness. Parameters of static and impact interaction of the carriage with a track in a place of butt joint which takes into account operational and constructive factors are defined.

“…New structures, where restrictions are generally not imposed, may also receive significant dynamic impacts from the passing load due to the span structure's structural and static design deficiencies. In this connection, creating a scientifically substantiated modern methodology for assessing the dynamic effects of moving loads on road bridge spans is an urgent task [2][3][4][5].…”

The article deals with the vibrations of a reinforced concrete bridge whose supports are located in soils with different properties under the action of overweight cargoes. The assumption is made that the structure deformed in the elastic zone when Hooke's law is valid. The Fourier method is used to solve the problem. The results are presented as graphs of changes in stresses and deflections along the coordinate and time, which are accompanied by analysis. When a concentrated load is applied, depending on the stiffness coefficient of the connection between the supports and the ground, stresses exceeding the limit load can occur in the middle of the beam cross-section. Thus, in the calculations, it is necessary to consider the nature of the interaction of the supports with the surrounding soils when calculating the beams for the action of moving loads.

“…The evolution of shear modulus in fatigue of both sandwiches is also described analytically using exponential and polynomial models. Many studies exist on the dynamic behavior of isotropic structures subjected to moving load in which the analytical and numerical methods are used [3][4][5][6]. However, the number of studies related to the vibration of beams with composite coats is relatively less [7][8][9].…”

This paper presents a numerical study of the free and damped forced vibration of simply-supported beams with composite coats subjected to a moving load by use of finite elements method. Three types of beam configurations, aluminum, composite and strengthened beam are investigated. The equation of motion of the beam is solved using the modal superposition method and integrated by applying the Newmark time integration procedure. Good agreements were achieved between the FEM and analytical solutions. The damped dynamic response, critical velocities and the dynamic amplification factor of the beam are calculated for different parameters such as the thickness ratio, the fiber orientation of the coat and damping ratio.
