Unsteady Vibro-Impact Loading
Mechanisms operating under multiple numbers of collisions, for which the frequency is of the same order as their eigenfrequencies, are usually referred to vibro-impact systems. These systems include, as a rule, units with external or internal one-side contacts that lead to the arising and vanishing of gaps accompanied by repeated impacts. Analytical solutions of vibro-impact problems are developed chiefly for steady processes in discrete mechanical systems (see, e.g., Kobrinsky AE and Kobrinsky AA 1973), and to a lesser extent, in solids (see Babitsky 1978, 1998; and also Pal’mov (1998). The DMM setting allows detailed study of these problems in conformity to the latter, including unsteady regimes.
