Abstract

This study explores the dynamic response and active vibration control (AVC) of an annular copper plate reinforced with graphene origami (GOri) auxetic metamaterials and integrated piezoelectric layers, under transverse mechanical shock. The governing equations are derived using Hamilton's principle and solved using the finite element method (FEM) and the Newmark algorithm. A parametric analysis examines the effects of GOri parameters, geometry, and boundary conditions on the dynamics. A low GOri mass fractions (<1 %) minimally impact the dynamics, while >2 % improves stiffness. The X-pattern optimally distributes the load, and a high folding degree has a varying impact depending on its distribution. The proposed control system, featuring a nonlinear fuzzy proportional–integral (PI) controller with adaptive gains cascaded with a proportional–integral–derivative (PID) controller, is compared to a velocity feedback system for vibration reduction. The proposed controller reduces maximum deflection by 80.39 %, outperforming the velocity feedback system (68.15 %). It also achieves a 48.4 % improvement in the integrated absolute error (IAE) index.

期刊介绍： Wave Motion is devoted to the cross fertilization of ideas, and to stimulating interaction between workers in various research areas in which wave propagation phenomena play a dominant role. The description and analysis of wave propagation phenomena provides a unifying thread connecting diverse areas of engineering and the physical sciences such as acoustics, optics, geophysics, seismology, electromagnetic theory, solid and fluid mechanics. The journal publishes papers on analytical, numerical and experimental methods. Papers that address fundamentally new topics in wave phenomena or develop wave propagation methods for solving direct and inverse problems are of interest to the journal.
