Oscillations of Mechanical Systems Affected by Moving Loads
Many mechanics problems result in consideration of the movement of one deformable body relative to another. As a specific case, the onedimensional movement of a rigid body or given load relative to the deformable foundation may be cited. The analytical solutions have been obtained for some 1-D tasks by Philippov at al. (1974), Kaplunov and Muravsky (1986), and by other authors. Using the DMM approach, the dynamic analysis of mechanical systems under loads arbitrarily varying and moving with variable speed does not present major difficulties. The general WFEM can also be applied to the study of 2-D waves induced by moving loads.
