We study the dynamical behavior of a system of two coupled mechanical oscillators with spring pendulums and
driven by a stick-slip induced vibrations. Each of the oscillator consists of the body placed onto a moving
belt/foundation, mechanical coupling associated with the body load pressed the belt depending on the body
movement as well as suspended spring pendulum. In addition, the influence of the presence of additional
electric/electromagnetic forces acting on the pendulums are analyzed. Different kinds of resonance behavior
can be found in the studied system, even if it is simplified to a single degree-of-freedom system. As a result, due
to many degrees-of-freedom and strong nonlinearity and discontinuity of the considered system, novel
nonlinear dynamical phenomena occur, both near and beyond to the resonance. The motion analysis for
different cases is carried out by employing standard numerical methods dedicated for nonlinear systems,
including both qualitative and quantitative methods, as well as original animations of the system dynamics
created in Mathematica. Understanding the role of coupling, transition between fixed points and energy
transition in the considered system can be potentially applied in other similar systems, especially in real
electro-mechanical systems, power system or in structural engineering
