Influence of nonlinear stiffness on the dynamics of a slender elastic beam under torsional oscillations
(2014)
This study focuses on analysing the effects of nonlinear torsional stiffness on the dynam-ics of a slender elastic beam under torsional oscillations, which can be subject to helical buckling.The helical buckling of an ...
Fundamental analysis on the intentional use of nonlinear stiffness in some dynamical systems
(2019-01-01)
Although nonlinearity in dynamical systems have been of concern for many years due to its unpredictable effects, researchers and engineers have recently begun to incorporate it into mechanical and mechatronic devices to ...
On the shock performance of a nonlinear vibration isolator with high-static-low-dynamic-stiffness
(Elsevier B.V., 2014-04-01)
The vibration isolation characteristics of a high-static-low-dynamic-stiffness (HSLDS) isolator, which has geometrically nonlinear stiffness, have been well established both theoretically and experimentally in the recent ...
On the Performance of a Two-Stage Vibration Isolation System Which has Geometrically Nonlinear Stiffness
(Asme, 2014-12-01)
Linear single-stage vibration isolation systems have a limitation on their performance, which can be overcome passively by using linear two-stage isolations systems. It has been demonstrated by several researchers that ...
The Characteristics of Vibration Isolation System with Damping and Stiffness Geometrically Nonlinear
(2016-10-03)
The paper concerns an investigation into the use of both stiffness and damping nonlinearity in the vibration isolator to improve its effectiveness. The nonlinear damping and nonlinear stiffness are both achieved by horizontal ...
An investigation of a two-stage nonlinear vibration isolation system
(2013-03-18)
This paper investigates the most desirable configuration of a two-stage nonlinear vibration isolation system, in which the isolators contain hardening geometric stiffness nonlinearity and linear viscous damping. The force ...
