“…For example, in [26], a cutteroscillator with a flexible holder in the X-axis direction was used to study the effect of changing the cutting speed on the suppression of regenerative chatter. In the study [15], the influence of the scheme of attaching dampers with tuned mass on the occurrence of vibrations in the process of turning a thin-walled cylinder, which in turn was an oscillator, was determined. In [27], a special design of an oscillator of low stiffness along the X-axis was used to study vibration in the turning process.…”

The work includes theoretical analysis of the design of a single-degree-of-freedom cutter-oscillator. An improved design, allowing for the adjustment of mass and overhang length, is proposed. An experimental stand for recording oscillograms of cutting-edge motion is developed. The proposed approach allows the cutter-oscillator operation to be effectively tuned depending on the cutting conditions. The results provide a flexible system for parameter estimation under different cutting conditions.

“…Theoretical analysis and experimental verification have demonstrated that the application of TMDs in reducing chatter during the turning of the thin-walled cylinder also shows a good control performance [15]. Vibration control analyses of a high-rise structure indicate the effectiveness of linearizing the equations of motion to obtain optimal control device parameters [16]. Moreover, the pendulum TMDs installed at the top of Shanghai Tower and Taipei 101 significantly mitigate the wind-induced vibrations, thereby improving the comfort levels of residents [17].…”

High-rise flue gas desulfurization towers are susceptible to wind loads, which can cause instability and failure in the along-wind and across-wind directions. The tuned mass damper (TMD) has been widely applied in the wind-induced vibration control of high-rise structures. To enhance the control performance and reduce the auxiliary mass of TMD, this study focuses on inerter-based dynamic vibration absorbers (IDVAs) for controlling the vibration response of a desulfurization tower. The dynamical equations of the tower–IDVA systems are established under wind loads, and a parameter optimization strategy for IDVAs is proposed by using the genetic algorithm. The performance of the traditional TMD and six IDVAs in the vibration control of the tower are systematically compared. Numerical simulations demonstrate that both the TMD and IDVAs can substantially mitigate the vibration response of the tower. However, compared to the TMD with the same response mitigation ratio, more than 34% of the auxiliary mass can be reduced by two optimal IDVAs. In addition, the energy dissipation enhancement and lightweight effect of the two IDVAs are explained through parametric studies.

“…Additionally, when the dynamic vibration absorber deviates from the ideal design state due to changes in the damping ratio or natural frequency of the main vibration system, the performance of vibration control also declines. Therefore, multiple dynamic vibration absorbers [4][5][6][7][8] were developed, for which two or more dynamic vibration absorbers are utilized in parallel on the main vibration structure, to improve the robustness of dynamic vibration absorbers and accomplish multi-modal vibration suppression. Despite a slight increase in the dynamic vibration absorber's vibration suppression frequency band due to this method, the band is still not particularly wide.…”

Structural vibration has always been a major concern in the engineering field. A dynamic vibration absorber in the form of contacts with adjustable stiffness (CDVA) offers effective vibration suppression and can improve conventional dynamic vibration absorbers with high sensitivity to frequency deviation and difficulty in adjusting the frequency. In this research, first, based on the theoretical model of the contact between a rubber ball and an inner cone, the feasibility of changing the axial contact state to change the structure’s natural frequency was verified using an ANSYS simulation. A theoretical model of the static contact stiffness between the ball and the inner cone was constructed using Hertzian contact theory and Hooke’s law, and a theoretical model of the cubic nonlinear elastic restoring force was used to characterize the stiffness properties of the rubber ball during compressive rebound. The steady-state frequency response equations of the main vibration structure were derived using the averaging method in conjunction with the two-degree-of-freedom dynamics model, and the stability of the solutions to the frequency response equations was obtained in conjunction with the stability determination criterion. Then, the impact of the CDVA’s design parameters on the nonlinear dynamic response of the primary vibration structure was simulated and analyzed. The resulting findings can serve as guidance for designing dynamic vibration absorber parameters. Based on the principles of ball-inner cone contact, a dynamic vibration absorber structure was proposed. A design test was conducted to verify the correctness of the contact stiffness model, and an experimental study was carried out to investigate the law of change in the dynamic stiffness and damping of the principle structure of CDVA under dynamic excitation conditions. Finally, the vibration test platform of the solidly supported beam structure was constructed, and vibration suppression tests of the CDVA in different compression states were conducted to investigate the tunability and feasibility of CDVA vibration suppression. The results showed that the dynamic vibration absorber had good vibration absorption characteristics and could be used for single-mode vibration suppression of multimodal main structures.
