Use of the dynamic stiffness method to interpret experimental data from a nonlinear system
(2018-01-01)
The interpretation of experimental data from nonlinear structures is challenging, primarily because of dependency on types and levels of excitation, and coupling issues with test equipment. In this paper, the use of the ...
Experimental Investigation of a Two-Stage Nonlinear Vibration Isolation System with High- Static-Low-Dynamic Stiffness
(2017-02-01)
A novel design of a two-stage nonlinear vibration isolation system, with each stage having a high-static-low-dynamic stiffness (HSLDS), is studied experimentally in this paper. The positive stiffness in each stage is ...
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 ...
Linearly Implicit Quantization-Based Integration Methods for Stiff Ordinary Differential Equations
(Elsevier, 2013-05-03)
In this paper, new integration methods for stiff ordinary differential equations (ODEs) are developed. Following the idea of quantization--based integration (QBI), i.e., replacing the time discretization by state quantization, ...
Increased Arterial Stiffness In Resistant Hypertension Is Associated With Inflammatory Biomarkers
(INFORMA HEALTHCARELONDON, 2015)
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 ...
Stiffness of lipid monolayers with phase coexistence
(American Chemical Society, 2013-08)
The surface dilational modulus (or compressibility modulus) has been previously studied for monolayers composed of pure materials, where a jump in this modulus was related with the onset of percolation as a result of the ...
On the detailed design of a quasi-zero stiffness device to assist in the realisation of a translational Lanchester damper
(2022-02-01)
A translational Lanchester damper is a device that adds damping to a structure at a point using a series combination of a viscous damper and a mass. The problem in the practical realisation of such a device is that a ...
Linearly Implicit Discrete Event Methods for Stiff ODEs
(Planta Piloto de Ingeniería Química, 2009-12)
This paper introduces two new numerical methods for integration of stiff ordinary differential equations. Following the idea of quantization based integration, i.e., replacing the time discretization by state quantization, ...
Design and test of an adjustable quasi-zero stiffness device and its use to suspend masses on a multi-modal structure
(2021-05-01)
In some applications, such as ground vibration testing in the aerospace industry, it is of interest to observe the modal behaviour of a slender structure while it is statically loaded. One way of statically loading such a ...
