Topic and aim. The aim of the work is to introduce into consideration a mechanical system that is a chain of oscillators capable of demonstrating hyperbolic chaos due to the presence of attractor in the form of the Smale–Williams solenoid. Investigated model. We study the pendulum ring chain with parametric excitation due to the vertical oscillating motion of the suspension alternately at two different frequencies, so that the standing wave patterns appear in the chain with a spatial scale that differs by three times.
