Abstract
Forced oscillations of elastic systems play an important role in modern technology. Forced are called such oscil-lations that arise when the external forces are applied to an elastic structure for a long time and do not depend on its initial state. Especially important, from a practical point of view, are forced oscillations of elastic systems caused by amoving load. Dynamic deflections obtained by elements of an elastic system from a moving load are much greater than its static deflections. Therefore, knowledge of the dynamic deformations of the system is very important for ana-lyzing its stress state. Accounting for dynamic factors plays a huge role in the design and construction of bridges, in housing construction, pipeline transport. In this paper, we study the function of dynamic deflections of a hinged-supported rectangular plate of dimensions a × b from a constant force P moving with a constant speed v-Const along a straight line. Formulation of the problem: to find the function of dynamic deflections of a hinged plate a × b from a given force P moving with constant velocity v along a straight line is parallel to the axis ox.
