Nonlinear dynamics of a new energy harvesting system with quasi-zero stiffness
Abstract: This paper presents the results of modelling a new nonlinear multi-stable QZEH (quasi-zero energy harvester) system for harvesting energy from vibrating mechanical devices. Detailed tests were carried out on the system model, which consisted of a beam and a system of springs, which were used to determine the potential of a quasiflat well. Two-dimensional…

Characterizing nonlinear characteristics of asymmetric tristable energy harvesters
Abstract: Ambient vibration conditions greatly influence the response of nonlinear energy harvesters. Recently, simulations and experiments have verified that tristable energy harvesters have excellent energy harvesting performance and complex nonlinear characteristics, which are important in broadening their effective operating frequency range. The response mechanism of the asymmetric tristable energy harvester is more complex than its…

Application of Bond Graphs in Modelling of the Energy Harvesting Systems from Vibrating Mechanical Devices
Abstract: This chapter presents the results of computer simulations of the system of energy harvesting from vibrating mechanical devices. Detailed model tests were carried out for the system of cantilever beams coupled with elastic elements. The end of one vibrating element is loaded with a permanent magnet, which defines a non-linear potential characteristic with the…
