Double pendulum response with energy transfer

This dataset belongs to the results from the article titled "Double pendulum response with energy transfer" in the journal " Eur. Phys. J. Spec. Top."by Grzegorz Litak, Marek Borowiec, Marcin Fronc, Magdalena Przybylska-Fronc, Jerzy Margielewicz, Damian Gaska, and S. Faruque Ali (https://doi.org/10.1140/epjs/s11734-025-01640-w). Abstract: Dynamical response of a double pendulum is studied and reported in this manuscript. The doublependulum system was innovated with a limiter (stopper) on the first pendulum, such that the rotationof the first pendulum is limited. The special focus is kept on the oscillations and rotations of the secondelement of the pendulum system. A simplified point mass model of the double pendulum system with theamplitude limiter on the first element of the pendulum is reported with harmonic horizontal excitation.Finally, the energy transfer to a twist damper is considered to show the possibility of energy harvesting. Forrelatively low frequencies, the results indicate resonance of the pendulum motion induced by the impact.In the higher frequency limit, we observe a good performance in the initial phase of motion. However, itis changed after transient time leading to the synchronized motion of the two elements of the pendulumsystem with fairly small amplitudes.We claim that the advantage of such a nonlinear structure with impactis related to the amplitude amplification mechanism designed in the first element of the pendulum system.1 Introduction
