The purpose of this paper is to explore analytically the influences of random fluctuations on
a two-degrees-of-freedom (TDOF) airfoil model with viscoelastic terms. To begin with, a …

In this paper, an approximate analytical technique is developed for determining the non-
stationary response amplitude probability density function (PDF) of nonlinear/hysteretic …

We investigate the stochastic response of a noisy bistable fractional-order system when the
fractional-order lies in the interval (0, 2]. We focus mainly on the stochastic P-bifurcation and …

A Galerkin scheme-based approach is developed for determining the survival probability
and first-passage probability of a randomly excited hysteretic systems endowed with …

A rotating cantilever sandwich-plate model with a pre-twisted and pre-set angle has been
developed to investigate the vibrational behavior of an aero-engine turbine blade with …

In this paper, an approximate semi-analytical approach is developed for determining the first-
passage probability of randomly excited linear and lightly nonlinear oscillators endowed …

The hybrid energy conversion mechanism can improve the performance of the energy
harvester compared to the single energy conversion mechanism. Meanwhile, the use of …

This paper aims to investigate the active vibration suppression of a fractional two-degree-of-
freedom viscoelastic airfoil (TDOFVA) model with a harmonic external force by means of the …

A vibration-based energy harvester is essentially a resonator working in a limited frequency
range. To increase the working frequency range is a challenging problem. This paper …

In this paper, the dynamical behavior of integer and fractional 4D hyperchaotic Rabinovich
system is studied. We use the Lagrange coefficient method to solve an optimization problem …
