Degenerate hope bifurcations in Chua's system
(2009-02-01)
In this paper we study the local codimension one, two and three Hopf bifurcations which occur in the classical Chua's differential equations with cubic nonlinearity. A detailed analytical description of the regions in the ...
The Occurrence of Zero-Hopf Bifurcation in a Generalized Sprott A System
(2020-01-01)
From the normal form of polynomial differential systems in R3 having a sphere as invariant algebraic surface, we obtain a class of quadratic systems depending on ten real parameters, which encompasses the well-known Sprott ...
Chandler wobble: Stochastic and deterministic dynamics
(2016-09-18)
We propose a model of the Earth’s torqueless precession, the “Chandler wobble,” as a self-oscillation driven by positive feedback between the wobble and the centrifugal deformation of the portion of the Earth’s mass contained ...
Nonlinear reduced-order modeling and bifurcation analysis of whirl flutter in a rotor-nacelle system
(2020-01-01)
Whirl flutter is an aeroelastic instability that can be affected by structural or/and aerodynamic nonlinearities. This instability may lead to potentially dangerous behaviors. In this study, a nonlinear reduced-order model ...
Impacts of stall and structural nonlinearities on the stability of aeroelastic systems
(2021-01-01)
The effects of stall, quadratic, and cubic nonlinearities in the pitch degree of freedom on the behavior of a two-degree of freedom aeroelastic system are investigated. The nonlinear governing equations of the considered ...
