In this paper, a moving-average method of smoothing noise based on complex exponential decomposition is applied to eliminate non-stationary signal and non-linear produced by Bouc–Wen model, which are added white Gaussian simulate the in measured signal. The uses sliding window cutting entire and/or into small segments considers that stable linear. decomposed series components via decomposition,...

Nonlinear state-space modelling is a very powerful black-box approach. However powerful, the resulting models tend to be complex, described by large number of parameters. In many cases interpretability preferred over complexity, making too complex unfit or undesired. this work, complexity such reduced retrieving more structured, parsimonious model from data, without exploiting physical knowledg...

In this paper, several variants of Differential Evolution, Particle Swarm Optimization and Genetic Algorithms are employed for the identification of a BoucWen hysteretic system that represents a full-scale bolted-welded steel connection. The purpose of this work is to assess their comparative performance in a highly nonlinear identification problem. Interesting results are produced that reveal ...

This paper presents theoretical modeling of a new magnetorheological elastomer (MRE) base isolator and its performance for vibration control. The elastomeric element of the traditional steel–rubber base isolator is modified to a composite layer of passive elastomer and MRE which makes the isolator controllable with respect to its stiffness and damping. The proposed variable stiffness and dampin...

Magnetorheological (MR) dampers are devices that can be used for vibration reduction in structures. However, to use these devices in an effective way, a precise modeling is required. In this sense, in this paper we consider a modified parameter identification method of large-scale magnetorheological dampers which are represented using the normalized Bouc-Wen model. The main benefit of the propo...

This paper presents a plausible reformulation and extension to the Bouc-Wen hysteresis model and gives an excellent summary and comparison of various theories of deteriorating constitutive models of hysteresis. A preliminary study on the effect of using overly simple hysteresis models (e.g., the bilinear model) when actual behavior includes strength degradation, stiffness degradation, and/or pi...

Abstract—In this paper, a one-dimensional (1d) Parallel ElastoPlastic Model (PEPM), able to simulate the uniaxial dynamic behavior of seismic isolators having a continuously decreasing tangent stiffness with increasing displacement, is presented. The parallel modeling concept is applied to discretize the continuously decreasing tangent stiffness function, thus allowing to simulate the dynamic b...

Application of Magneto-Rheological (MR) dampers in semi-active vibration dynamics control of a multi-cart system is studied. The dynamics and vibration behaviour of a two cart system is investigated mathematically and an experimental test-rig is employed to verify the model, experimentally. The Bouc-Wen model is utilized to represent the mathematical behaviour of MR damper. Different types of s...
