“…Again, the developement of the experimental set up is quiet noble one with the T use of PLC controller. The errors(Results and Discussion section) which are obtained from this study are quiet less as comparison to the others works like Jena et al [8,9]. The main points of this paper are as following: The effects of amount of cracks, crack depth and crack position on the dynamics of cracked beams have been scrutinized.The impact of velocity and mass of moving load have been explored.…”

“…From the work by Jena et al [8], it is understood that different crack types can affect the vibration characteristics of damaged beams, especially, the influence of the inclination angle of the crack was proposed as a novelty. Work by Jena and Parhi [9] includes numerical, FEA and experimental analysis of the cracked structures under moving mass through a comparative attitude. They investigated the effects of different types of cracks.…”

In this study, the influences of crack parameters like crack location from the left end, crack height, number of cracks and the magnitude of mass and the velocity of the transit load on the vertical displacements of the cracked simply supported beams subjected to transit mass are investigated. The transverse open cracks with numerous damage scenerios are considered for the mathematical modelling of the system. The governing equations of motion for the system have been obtained and the equations have been solved by the help of Duhamel integral technique. The theoretical formulation has been exemplified with numerical studies. By utilizing ANSYS Workbench 2020, transient structural analysis has been carried out. The mode shapes and the frequency ratios of damaged simply supported beam have also been determined. To validate the numerical and FEM models, the experiments with damaged beams have been carried out in the laboratory. It has been proven that the results of the theoretical and FEM models are well convergent with the experimental data. The results gathered from the numerical analysis, FEA as well as experimental study have been presented with comparative graphs and tables. The outcomes of the examinations have been interpreted in the conclusions part. It has been observed that subject parameters are of considerable significance on the time dependent response of the cracked beams.

“…Wang et al [9] developed a high-order shear deformable beam model and investigated the transient response of a sandwich porous beam when acted upon by a non-uniformly distributed moving mass. Jena, Parhi and other authors [10][11][12][13][14][15] studied cracked structures subjected to moving mass problems. Besides, Parida, Jena and others [16][17][18][19][20][21] investigated the dynamic and static problems of composite structures.…”

The dynamic characteristic of a space rotating flexible arm with moving mass were investigated. The space arm with moving mass can rotate around the fixed end in horizontal and vertical planes simultaneously. And the lateral deflections of the arm in the two planes were considered. The equations of the structure were derived by the Lagrange’s equation with the assumed mode method. And a system of binary second order linear differential equations is gotten. Based on the central difference method, a conditionally stable algorithm for solving the equations is established. Due to the coupling of lateral displacements of the arm in horizontal and vertical planes, the increase of the angular velocity in one plane will increase the lateral displacements in the other plane. When the angle between the arm and the horizontal plane increases, the component of gravity along the normal direction of the beam will decrease, resulting in a decrease in lateral displacements in vertical plane, however, it will lead to a decrease in stiffness in horizontal plane and thus an increase in lateral displacements. Compared with moving mass, moving load ignores the influence of inertial force, so the calculation results of moving mass and moving load are different. The conclusions provide calculation basis for the design of similar structures.
