Various pendulum-based systems are very popular for their low cost, reliability and simple maintenance. However dynamic behaviour of such substructure is significantly more complex than it is supposed by widely used simple linear single degree-of-freedom models. The paper compares the mathematical model of the spherical pendulum, considered as strongly non-linear dynamic system with kinematic external excitation in the suspension point and experimental model, equipped with viscous damping independent in the both directions.
