The nonlinear behavior of semi-active magneto-rheological (MR) absorbers should be described for improving control algorithms. Also, overheating in the working conditions MR absorber due to current excitation and high damping velocity seriously changes characteristic fluid causes problems controllability. relationship between performance temperature must defined algorithms that when used a syst...

This paper proposes a procedure to identify stochastic Bouc-Wen model for describing the dynamics of structure assembled by bolted joints considering vibration data. The proposed identification approach is expressed into Bayesian framework take account data fluctuations related uncertainties in measurement process. calibration parameters uses analytical expressions higher-order frequency respon...

This paper presents a comparative study between different nonlinear damper models, developed for semi-active Electro-Rheological damper. The first model is by extending the hysteresis to obtain dynamic characteristic of To improve accuracy capturing damper’s behavior, Bouc-Wen using parameter-varying functions control input and state. One key points in proposed models describe dynamics controll...

The coupling with external mechanical systems such as oscillating masses working tuned mass dampers, dynamic absorbers, elasto-plastic and rigid walls is an effective method to reduce the displacements drifts of structures under loads. An alternative provided by structure independent, auxiliary system. This paper investigates seismic behaviour a rigidly coupled yielding system harmonic ground e...

The nonlinearity behaviour of magnetorheological fluid (MRF) can be described using a number established models such as Bingham and Modified Bouc-Wen models. Since these require the identification model parameters, there is need to estimate parameters' value carefully. In this paper, an optimization algorithm, i.e., Particle Swarm Optimization (PSO) utilized identify models' parameters. PSO alg...

Abstract This paper examines the effect of structural damage on practical/computational identifiability parameters that define nonlinear models building structures subjected to earthquake‐induced base motions. The objective is determine level physical expected successfully estimate restoring force models. For this purpose, analyses aim if a hysteretic (Bouc‐Wen type) model can be identified wit...

Natural hazards such as earthquakes have threatened the life of human beings during the history.As a consequence, the vibration mitigation of structures has caught great importance. Activecontrol of structures is one of the rapidly emerging areas in the concept of structural control. Thispaper presents a control method to deal with this subject when the dynamics of the structure ishysteretic an...

The collaborative robot market has experienced rapid growth, leading to advancements in compliant actuation and torque control. Magneto-rheological (MR) clutches offer a hardware-level solution for achieving both compliance control through adjustable coupling between the input output of MR clutch. However, presence frequency-dependent magnetic hysteresis makes controlling challenging. In this p...
