“…The main purpose of the explored curves in Figures 20,21,22,23,24,25 is to investigate the time histories of the achieved asymptotic solutions x, r, and θ, taking into account the above-selected values of the parameters c 1 , c 2 , c 3 , ω 1 , and ω 2 . Decay waves are plotted in parts of Figure 20, in which the solution x is impacted by the values of c 1 and the amplitude of the graphed waves decreases with the increase of c 1 values, as demonstrated in part (a).…”

“…In Reference 24, vibration absorbers were developed as energy-harvesting devices and vibration-damping systems to suppress undesired vibrations and generate induced voltages that can be used in low-voltage applications such as wireless sensors. In Reference 25, a numerical analysis of a semi-active suspended vibration absorber, or harvesting system, was performed. The primary objective was used to dampen the vibrations of the primary structure, and the secondary objective was considered an absorber that simultaneously harvested energy from the vibrations.…”

This article studies the motion of a three degrees-of-freedom (DOF) dynamical system, which consists of two parts, a dynamic part, and an electromagnetic harvesting device. The composition of the system depends on the magnet oscillating in the coil of this device. An electric potential is exerted because of the electromotive force to obtain energy harvesting (EH). Lagrange's equations (LE) are used to derive the system’s equations of motion (EOM), which are solved analytically up to a third-order of approximation using the multiple-scales method (MSM). These solutions are considered novel, in which the mentioned method is applied to a novel dynamical system. The gained are confirmed through comparison with the numerical solutions of the EOM to reveal a high degree of consistency. To establish the system’s solvable conditions and modulation equations (ME), three scenarios of primary external resonance are investigated simultaneously. Certain diagrams of time histories for the amplitudes and phases of the examined dynamical system are plotted to show their behaviors at any given instance of time. The Routh–Hurwitz criteria (RHC) are used to establish the stability and instability regions in light of the graphs of resonance response curves. The presence of an energy harvester in dynamic devices helps us to convert vibrational motion into electrical energy that can be exploited in several applications in a variety of daily tasks, including structural and environmental monitoring, military applications, space exploration, and remote medical sensing.

“…In Ref. 30, numerical analysis of a semi-active suspension mounted absorber or harvested system has been studied, in which the primary objective is used to damp the primary structure’s vibration and the secondary objective is to simultaneously harvest energy from the absorber’s vibration. The pendulum-tuned mass absorber is adjusted by a magnetic levitation harvester.…”

This work focuses on vibration alleviation and energy harvesting in a dynamical system of a spring-pendulum. The structure of the pendulum is modified using an independent electromagnetic harvesting system. The harvesting depends on the oscillation of a magnet in a coil. An endeavor has been made to get both the energy harvesting and mitigation of vibration efficacy of the harvester. The governing kinematics equations are derived using Lagrange’s equations and are solved asymptotically using the multiple scales method to achieve the intended outcome as new and precise results. The resonance states are classified, and the influence of various parameters of the studied system is analyzed. Fixed points at steady states are categorized into stable and unstable. The time behavior of the solutions, the modified amplitudes, and phases are examined and interpreted in the light of their graphical plots. Zones of stability and instability are concerned, in which the system’s behavior is stable for a wide range of used parameters. This model has become essential in recent times as it uses control sensors in industrial applications, buildings, infrastructure, automobiles, and transportation.
