PARAMETRIC AND NONPARAMETRIC APPROACH OF MAGNETO-RHEOLOGICAL DAMPER MODELLING: A REVIEW

Magneto-rheological (MR) fluid is a smart material that can quickly alter its rheological characteristic under magnetic field impact and has witnessed a notable surge in attention and developments in recent years. The versatility of this material has allowed it to be used in MR fluid base devices, especially MR dampers, and has sped up its development in various technical applications. The MR damper works in conjunction with a controller to effectively reduce the vibrations by utilizing magnetic forces in both passive and active modes. Monotube, twin-tube, and double-ended MR dampers are the most widely used types of MR dampers, and each of them has a unique characteristic. A thorough and clear understanding of how the MR dampers behave under different conditions is necessary to model the MR damper. Both parametric and nonparametric approaches may be applied in modelling the MR damper. This review intends to discuss the advantages and disadvantages of both parametric and nonparametric approaches through a comprehensive analysis that has been made.
