dc.description.abstract-translatedThe paper presents a numerical model of a nonlinear quasi-zero stiffness (QZS) vibration isolator using an Euler-buckled beam as a negative stiffness corrector. The Absolute Nodal Coordinate Formulation (ANCF) is employed to accurately capture large deformations, geometric nonlinearities, and post-buckling behavior without relying on small-deformation assumptions. Thanks to its fully nonlinear formulation and constant mass matrix, ANCF enables reliable static and dynamic analysis of the QZS region, particularly near instability points and under larger excitation amplitudes. The approach provides a robust framework for advanced simulation and optimization of QZS vibration isolation systems.en
