Abstract | ||||
ABSTRACT The statics and dynamics of mechanical systems with contact dry friction, representing the nonlinear mechanism of the energy dissipation, is a new actual direction in the nonlinear mechanics of deformable solids. Damping effects of this sort can appear on the boundaries of rough layered environments or in relative movements of one body along a surface of another. Such kind of tasks come to consideration of the hyperbolic type equations of a nonlinear system and connected with distribution and attenuation of nonlinear waves. Analytical results for the distribution of nonlinear waves in the system with contact dry friction under the influence of cyclic loads were obtained. The class of loads under which the system shows subharmonic and ultraharmonic oscillations was determined. Based on the results of obtained decisions the following conclusion has been made: there is a class of cyclic loads with the frequency to arbitrary integer times which differs from the frequency of its own fluctuation of system under the action of which the system performs established or resonant fluctuations. | ||||
