Renewable distributed generators (RDGs) have made inroads in recent power systems
owing to the environmental effect of traditional generators and their high consumption of …

The ability to power low-power devices and sensors has drawn a great deal of interest to
energy harvesting from ambient vibrations. The application of variable-length pendulum …

This study examines the motion of a spring pendulum with two degrees-of-freedom (DOF) in
a plane as a vibrating system, in which its pivot point is constrained to move along a …

This research examination aims to demonstrate for the first time the multiple nonlinear
equilibria attributed to the curvature sensitivity in thermomechanical stability characteristics …

Purpose This article concentrates on the oscillating movement of an auto-parametric
dynamical system comprising of a damped Duffing oscillator and an associated simple …

In this work, the influence of a piezoelectric device on the planar motion of a two-degrees-of-
freedom (DOF) dynamical system is examined. This system comprises a nonlinear dam** …

This work studies a two degrees-of-freedom (DOF) dynamical system whose governing
system is solved analytically using the multiple scales approach (MSA). The solvability …

This paper studies the dynamics and integrability of a variable-length coupled pendulum
system. The complexity of the model is presented by joining various numerical methods …

This paper investigates the dynamics and integrability of the double spring pendulum, which
has great importance in studying nonlinear dynamics, chaos, and bifurcations. Being a …
