This manuscript uses the generalized Khater (GK) method and trigonometric quintic B-spline (TQBS) scheme to study calculations approximate solutions of complex nonlinear Fokas–Lenells (FL) equations. model describes propagation short pulses in optical fibers. Many novel computing have been obtained. The absolute, real, imaginary values some are plotted two three-dimensional density graphs explain dynamic behavior fiber. use constructed analytical evaluate initial boundary conditions allows...
This article investigates the motion of double nonlinear damped spring pendulums with 3DOF in which its pivot point moves an elliptic trajectory. The controlling system is derived applying Lagrange's equations and solved asymptotically up to third approximation utilizing multiple scales technique. arising resonance cases are categorized view solvability conditions modulation obtained. steady-state solutions accordance stability instability criteria examined. novelty this work lies obtaining...
This work is meant to investigate and control the nonlinear dynamical behaviours of a asymmetric rotating shaft system. The studied system modeled as having both quadratic cubic nonlinearities excited at primary resonance. A linear proportional-derivative controller introduced eliminate suppress lateral vibrations shaft. influences different parameters on oscillatory considered are explored. main obtained analytical results showed that uncontrolled may respond with forward backward whirling...
Abstract In this paper, we study a multiple scales perturbation and numerical solution for vibrations analysis control of system which simulates the nonlinear composite beam model. System second order differential equations with nonlinearity due to quadratic cubic terms, excited by parametric external excitations, are presented. The controller is implemented one frequency at primary resonance where damage in mechanical probable. Active applied system. (MSP) method obtain an approximate...
Based on the one-dimensional elastic theory, radial vibrations of cylindrical isotropic embedded in an medium are studied paper. The effect magnetic field hollow cylinder with rotation is researched as well. equation elastodynamic solved terms displacement. frequency obtained when boundaries free and fixed; mixed boundary condition numerically examined. determination concerned eigenvalues natural case harmonic vibrations. frequencies were explored. It was shown that dispersion curves guided...
