In this paper the vibration suppression problem relative to the vertical motion of road vehicles is investigated. In particular, the goal of the research is to design control laws for active suspension systems of road vehicles in order to reduce unwanted vibrations induced by a rough road profile. The road vehicle has been represented with a quarter-car model whereas the suspension system has b...

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...

The tracking control accuracy of the piezoelectric actuator (PEA) is limited due to its inherent hysteresis nonlinearity. A new piezoelectric-actuator model is synthesized based on two first-order transfer systems in parallel with two tuned parameters determined from one experiment. Two open-loop tracking controllers are implemented with the proposed model to compensate the hysteresis of linear...

To compensate for missing functions of lower extremity amputees, this paper proposes a model of an intelligent bionic leg semi-actively controlled by a magnetorheological damper (MRD). A mechanical structure of the leg is designed, and with the help of Bouc-Wen model, a MRD forward dynamics model is constructed for simulation. On the basis of data obtained from simulations, the MRD inverse dyna...

An analytical approach based on modified Bouc-Wen-Baber-Noori model has been proposed in this paper for predicting the hysteresis behavior of reinforced concrete beamcolumn joints with limited transverse reinforcement. The analytical model presented in this research is able to capture the characteristics of non-seismic detailed beam-column joints such as stiffness and strength degradation and p...

To deal with the challenges that classical Bouc–Wen model fails to precisely characterize amplitude-dependent hysteresis and asymmetric hysteresis, an improved variable parameters is presented. The proposed introduces terms parameter functions related sinusoidal excitation amplitudes into model. It has a relatively simple mathematic form can be easily identified applied for inverse feedforward ...

The paper presents an application of the Extended Energy-dependent Generalized Bouc–Wen model (EEGBW) to simulate experimental cyclic response Cross-Laminated Timber (CLT) panels. main objectives are assessing sensitivity quadratic error between and numerical data EEGBW parameters, showing fitting performance in matching CLT panels, highlighting stability nonlinear dynamic analysis with seismic...
