Mass design of nonlinear energy sinks

Guo-Xu Wang et al.

Summary: This paper investigates the optimal mass design of nonlinear energy sinks (NES) using the non-dominated sorting differential evolution algorithm and parameter sensitivity analysis. The study reveals the relationship between optimal mass and vibration mitigation effects under different damping and harmonic excitation strengths. The findings demonstrate the important role of mass design in achieving decent vibration reduction in engineering structures.

An inerter-enhanced asymmetric nonlinear energy sink for response mitigation of structures subjected to harmonic and seismic ground excitations

Jingjing Wang et al.

Summary: This study proposes asymmetric nonlinear energy sink-inerters (ANESIs) to improve the applicability of mass dampers in control problems facing different types of uncertainties. Analyzing the dynamics of the ANESI system under harmonic and seismic ground excitations, the study updates the theoretical model of ANESIs, carries out analytical investigations, and proposes a design method for the ANESI system. Results show ANESIs outperform linear and nonlinear counterparts in seismic applications.

Tunable-with-energy intense modal interactions induced by geometric nonlinearity

Alireza Mojahed et al.

Summary: Modal interactions in nonlinear systems can be exploited in various applications such as vibration and shock mitigation, targeted energy transfers, and acoustic/stress wave tailoring. By examining the geometric nonlinearity of an initially inclined element, it was found that strong modal interactions can be induced by tuning the nonlinearity to be softening, hardening, or a combination of both, depending on the initial angle of inclination and the energy-level.

Effectiveness and robustness of an asymmetric nonlinear energy sink-inerter for dynamic response mitigation

Jingjing Wang et al.

Summary: Nonlinear energy sinks (NESs) have shown better performance than tuned mass dampers in mitigating undesired responses against changes in structural frequencies. However, the dilemma of gaining frequency robustness at the cost of energy sensitivity and the large masses of devices required for civil engineering structures hinder the applications of existing NESs. To address the issue of lacking energy robustness and leverage inerters to reduce physical mass, an asymmetric NES-inerter (Asym NESI) is developed in this study.

Evaluation of a pendulum pounding tuned mass damper for seismic control of structures

Wenxi Wang et al.

Summary: The study evaluates the performance of PPTMD in controlling vibrations of structures under ground motions. Optimum parametric formulas are proposed for optimal PPTMD design, showing that PPTMD effectively suppresses structural responses even under detuning situations. The effectiveness of PPTMD as a single-mode controller is demonstrated when the target mode is mainly excited under seismic excitations.
