Academic Seminar: From Tuned Mass Dampers to Energy Transfer in Vibroimpact Systems

From Tuned Mass Dampers to Energy Transfer in Vibroimpact Systems

Professor Daniil Yurchenko, University of Southampton

3:00 p.m., Wednesday, July 15, 2026

This presentation examines vibration mitigation and energy transfer in linear and nonlinear dynamical systems subjected to deterministic and stochastic excitation. The first part considers narrow-band-excited systems equipped with tuned mass dampers, with particular attention to different topologies of spring and damper connections between the primary structure and the absorber. The performance of the resulting non-traditional dampers is compared with that of a classical tuned mass damper through exact analytical development and computational optimization. The results illustrate how topology can be exploited for vibration mitigation in stochastic dynamical systems. The second part addresses targeted energy transfer (TET) in vibroimpact systems, in which a ball travels freely inside a harmonically excited capsule. TET can be used for effective vibration mitigation, energy harvesting, and other relevant applications in mechanical, electrical, and biological systems at both macro- and microscales. In the system considered, dielectric energy-harvesting elements are activated during impacts, enabling part of the transferred vibration energy to be converted into electrical energy. The results show that higher mass ratios between the ball and the capsule can unexpectedly degrade performance, introducing adverse effects that counteract the intended benefits of energy absorption.

Dr. Daniil Yurchenko joined the University of Southampton in 2021 and has led the Dynamics Research Group at the Institute of Sound and Vibration Research. His research expertise spans nonlinear and stochastic dynamics, vibration mitigation, and the mathematical and experimental modeling of complex dynamical systems. He received his PhD in Mechanical Engineering from Worcester Polytechnic Institute in the United States. In 2008, he received the Young Scientist Award from the Russian Presidential Council for Science and subsequently became a full professor in the Department of Mathematical and Physical Sciences at Peter the Great St. Petersburg Polytechnic University. He has led multiple industry-sponsored research projects and has undertaken research funded by the UK Engineering and Physical Sciences Research Council (EPSRC) and the Royal Society, as well as a Marie Skłodowska-Curie Actions postdoctoral fellowship project funded by the European Union. Dr. Yurchenko has published more than 200 peer-reviewed papers and has delivered invited and plenary presentations at numerous international conferences. He is a Fellow of the International Institute of Acoustics and Vibration and serves as an associate editor of Mechanical Systems and Signal Processing, Communications in Nonlinear Science and Numerical Simulation, and Vibration Testing and System Dynamics. He also serves on the editorial boards of Probabilistic Engineering Mechanics, International Journal of Dynamics and Control, Vibration, and Energies.
