Recently, magnetorheological elastomer (MRE) has been paid increasingly attention for vibration mitigation devices with the benefits of low power cost, fail safe performances, and fast responses. To make full use of the striking advantages of MRE device, a highly precise model should be developed to predict its dynamic performances. In the work, an MRE isolator in shear–squeeze mixed mode is developed and tested under dynamic loadings. The nonlinear performances in various displacement amplitude and currents are shown. An artificial neural network model with a back-propagation algorithm is proposed to characterize the nonlinear hysteresis of MRE isolator for its implementation in vibration control applications. This model utilized the displacement, velocity, and applied current as inputs and output force as output. The results show that the proposed model has high modeling accuracy and can well portray the complicated behaviors of MRE isolator with different excitations, which shows a fundamental basis for structural vibration control.


In these work it is said that artificial systems are connected to finding of calamitous imperfections in the advanced piece of a nonlinear blended mode circuit. The methodology is exhibited on the case of a moderately mind boggling sigma-delta modulator. A lot of shortcomings are chosen first. At that point, issue lexicon is made, by reproduction, utilizing the reaction of the loop path to an info incline flag. This spoken to type of a carry-into table. Counterfeit neural system is then prepared for displaying (retaining) the look-into table. The conclusion is carried out so the artificial neural network is energized by broken reactions so as to introduce the deficiency codes at its yield. There were no blunders in recognizing the shortcomings amid conclusion.
