This paper provides a full-scale parametric study on the dynamic characteristics and unstable regions of a functionally graded graphene platelet-reinforced (FG-GPLR) aluminum-based truncated conical shell under 1:1 internal resonance condition. The modified Halpin-Tsai mechanical model is applied to predict the effective physical property parameters of the FG-GPLR aluminum-based truncated conical shell under different graphene distributions (GPL-U, GPL-O, and GPL-X). First, under the influence of temperature, based on the first-order shear deformation theory and von-Karman nonlinear strain-displacement relations, the motion equations of the simply supported FG-GPLR aluminum-based truncated conical shell are obtained using Hamilton's principle and the Galerkin method. Second, by applying the multi-time scale perturbation analysis method, the coupled averaged equations in polar coordinates are derived. Subsequently, amplitude-frequency and force-amplitude response curves are plotted to study the effects of various parameters, including graphene distribution, graphene weight fraction, in-plane excitation amplitude, tuning parameter, structural dimensions of GPLs, temperature, damping coefficients, and phase angle, on the vibration characteristics. Finally, the unstable regions of the zero solution under different parameter variations are analyzed based on the Jacobian matrix. The results indicate that the GPL-X distribution is the optimal graphene distribution. The weight fraction of graphene is the primary factor influencing the vibration characteristics and unstable regions.

In this contribution, the Dynamic Mode Decomposition with control (DMDc) is used to derive a surrogate model of a continuous PHA biopolymer production process based on a recently published complex process model. Here, snapshot simulation data of the original model is processed to obtain a linear surrogate model formulation using delay coordinates. The quality of the surrogate is statistically validated within simulation studies. Additionally, the influence of the of the order of delay coordinates is investigated. It is shown, that the highly nonlinear dynamics of the PHA-manufacturing process can be approximated accurately by the DMD-based model even for large variations of initial conditions and control variables. This offers the opportunity to apply well-studied and established tools from robust and optimal control in future investigations. Copyright © 2025 The Authors.

The transmission of vibrations from hand-held impact machines (HHIM) to the human hands is undesirable and can cause serious injury, including amputation of the hand. Therefore, it is crucial to analyze and develop efficient vibration control methods to curb vibration transmission to the hands from a HHIM. The first step towards developing an efficient vibration control method is to obtain a model that can accurately predict the dynamics of the HHIM. Thereafter, a numerical or theoretical study of the HHIM-vibration control device model can reveal the devices effectiveness. To address the need for a HHIM model, we analyze a reduced order model of a HHIM which incorporates the vibro-impact interactions of the HHIM bit with the ground. The effectiveness of a cubic nonlinear absorber in the HHIM is then studied via a lumped mass parameter model consisting of a vibro-impact tool model coupled to the hand-arm system (HAS) and a cubic nonlinear tuned vibration absorber (NLTVA). A detailed numerical analysis of this system is performed to show the rich nonlinear dynamics of the system. The results from this study show that an appropriate selection of absorber parameters can effectively change the amplitude and periodicity of vibrations at the hand, thereby proving the potential of a cubic nonlinear absorber as a viable vibration control option.

A design approach for quasi-zero stiffness (QZS) nonlinear absorbers for rotor system vibration suppression is proposed in this paper. An example of the QZS nonlinear absorber is designed for a single-disc rotor system considering gyroscopic. The nonlinear absorber consists of a rigid mass ring and four circumferentially distributed nonlinear springs, which are coaxially mounted and rotated together with the disc. The equations of motion of the rotor system with the QZS nonlinear absorber are derived by the Lagrange’s equation. According to the motion equations, it shows that the rigid mass ring reveals a negative stiffness due to the centrifugal forces generated by its vibration. The quasi-zero stiffness is realized by combining the positive stiffness provided by the nonlinear springs and the negative stiffness generated by the centrifugal forces. The stability of the rotor system is compromised at high rotational speed due to the speed-dependent negative stiffness provided by the centrifugal force. Thus, the influence of the linear and nonlinear stiffness on vibration suppression and stability of the rotor system are discussed. The present results indicate that increasing the linear stiffness appropriately can enhance the decay rate of the peak vibration and improve the stability of the rotor system. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

A bird-inspired nonlinear oscillator (BINO) is proposed for low-frequency vibration control and energy harvesting of bridges. By integrating the spring into the oscillator, the space utilization rate and reliability are further improved. Theoretical analysis and experimental results show that BINO with triboelectric nanogenerator damper (BINO-TENGD) with quasi-zero stiffness (QZS) has excellent low-frequency vibration isolation performance and stable output voltage. In addition, BINO-TENG can produce resonance phenomenon in the frequency range of 3-8 Hz under bistable condition, and obtain high output. Finally, BINO-TENGD under QZS condition is applied to the beam bridge, and the results show that adding BINO-TENGD to the beam bridge is beneficial to suppress vibration. Therefore, BINO has a certain application prospect in the fields of bridge low-frequency vibration control, vibration detection and energy harvesting. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

In engineering, vibration is ubiquitous. In order to avoid damage caused by vibration to some devices, passive vibration absorbers are usually used for vibration reduction in engineering. The concept of nonlinear energy sink (NES) has been proposed for a long time. However, most previous studies on NES have typically conducted vibration reduction research by coupling a single-degree-of-freedom (1DOF) NES with a single-degree-of-freedom primary system. This paper proposes a vibration control strategy using a limited amplitude series NES. A dynamic model using a limited series NES was established for the two-degree-of-freedom (2DOF) primary system. The influence trend of the parameters of the limited series NES parameters on the vibration control effect was studied through dynamic analysis. The results show that the amplitude-limiting series NES has a better vibration absorption effect and stability than the ordinary series NES under the same mass of the total vibration absorber. This study provides a new and efficient vibration control strategy. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The floating raft vibration isolation system has the problem of multi-frequency vibration in the process of vibration. The existence of multi-frequency vibration makes it difficult to apply linear vibration absorption. In this paper, the nonlinear vibration absorption is applied to the floating raft vibration control, and the floating raft vibration control strategy using multiple nonlinear energy sinks (NESs) distributed arrangement is proposed for the first time. Considering that the base of the original floating raft system has elastic support, the natural frequencies and modes of the floating raft system are analyzed, and the dynamic models of the floating raft system with different distribution modes of NES are established. Through dynamic analysis, the influence laws of NES distribution on floating raft vibration control are compared. Based on the vibration reduction of low-order and high-order modes, the NES layout mode is analyzed. The results show that the distributed nonlinear energy sinks arrangement can effectively control the vibration of floating raft, and has good vibration damping effect on all modes of floating raft. The floating raft vibration attenuation for low-order and high-order modes should be arranged in different NES placement modes. In conclusion, the study of this paper provides a new and efficient control strategy for floating raft vibration. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

This paper presents a new understanding and development related to nonlinear inertia and its effect in coupling with an X-shaped anti-vibration mechanism, which is validated by prototyping and experiments. The new inertial unit integrated in a well-designed X-shaped mechanism allows larger excitation displacements and more adjustable inertia ratios, resulting in significantly lower vibration transmissibility and resonance peak, and produces three different typical nonlinear inertia forms. A key parameter indicator (Ratio of Inertia) is proposed to identify and indicate the different types of nonlinearities, and the resulting beneficial effects are explored. The performance improvement in dynamics with respect to the linear counterpart is evaluated for different nonlinear inertia forms. The results show that: (a) The U-shaped symmetrical nonlinear inertia coupling with X-shaped mechanisms can provide better vibration isolation performance at low frequency;(b) High-frequency transmissibility can be tuned to different level, indicating a tunable band-suppress property, which is a unique property discovered in this study;(c) the nonlinear inertia contributes significantly to tune the interactive force between vibration source and object in the low frequency range ( © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
