“…Nonlinear isolators, owing to their wider frequency bands and superior isolation efficiency relative to linear isolators, have emerged as a focal point of research [1,2]. Within this class, quasi-zero stiffness (QZS) represents a typical nonlinear vibration isolation feature [2], capable of imparting high-static-low-dynamic-stiffness (HSLDS) properties and furnishing a range of anti-vibration structures such as beams [4,5], cam-roller [6,7], horizontal springs [8][9], and magnets [11][12][13]. Bio-inspired vibration isolators, on the other hand, draw inspiration from natural systems to create effective and efficient solutions for vibration control, including achieving QZS characteristics [14].…”

This paper presents a novel nonlinear anti-vibration ring with deformable crescent-shaped cross-sections (NAVR-DCCS) inspired by the petiole of palm leaf. The proposed NAVR-DCCS exhibits markedly enhanced nonlinear quasi-zero stiffness through deformable cross-sections, which endow it with advantageous vibration isolation attributes. A comprehensive investigation of the structural nonlinearities and dynamic behaviors of the NAVR-DCCS is undertaken, with emphasis on the principle of cross-sectional deformation and its nonlinear stiffness properties. This study explores the influence of pertinent parameters on the nonlinear characteristics and displacement transmissibility. Tensile-compression testing and transmissibility measurements are conducted to verify theoretical calculations, and the experimental results are found to be in congruity with theoretical predictions. The beneficial nonlinear characteristics of the NAVR-DCCS hold promise for providing a passive vibration isolation methodology, representing a potentially innovative solution with broad-reaching applicability and utility across diverse research domains.

“…With the prosperous advancement of vibration theory, engineers attempted to introduce nonlinearity in engineering to subdue the harmful vibration of formation. Within this background, scholars designed various nonlinear equipment and deeply studied its vibration behaviors (Cheng et al, 2016; Fulcher et al, 2014; Leblouba et al, 2019; Niu and Chen, 2021; Yan et al, 2018). To understand the potential application of nonlinear equipment in engineering practice, a large number of scholars analyzed the transverse vibration of beam frameworks with various nonlinearities, in which the beam structures are one of the most important units in various engineering fields.…”

To exploit the potential application of supporting nonlinearity in marine engineering, an attempt is made to establish the transverse forced vibration analysis model of a double-beam system supported by a spring-mass system that is nonlinear. This kind of vibration system consists of two beam sections, boundary supports, a coupling component, and a nonlinear spring-mass arrangement. The variational approach and the generalized Hamiltonian concept are used to develop the governing equations of such a double-beam system. The Galerkin truncation method (GTM) is a technique for obtaining the governing equations’ residual equations. By solving the associated residual equations numerically, the nonlinear responses of the double-beam system can be figured out. The GTM has good solidity and correctness in the prediction of the vibration system’s forced transverse vibration. The dynamic responses of the double-beam structure supported by a spring-mass system that is nonlinear are subtle to their initial calculation values. Appropriate parameters of the nonlinear support will subdue the level of vibration at the boundary of the double-beam system. In contrast, unsuitable parameters of the nonlinear support motivate complex dynamic responses of the double-beam system and harmfully influence the vibration repression at the boundary of the vibration system.
