DESIGN AND EXPERIMENTAL STUDY OF SEMI ACTIVE SYSTEM OF MR DAMPER FOR VIBRATION CONTROL
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 4
Abstract
Semi active control systems that offer the reliability of passive control systems, as well as the versatility and adaptability of active control systems have received significant attention for structural vibration control. Magneto-Rheological (MR) fluid dampers have emerged as such a class of semi active damping devices. By activating the MR fluid contained in the device through magnetic field, it can reversibly change from liquid to semisolid in milliseconds, which results in a continuously controllable device. The designs of nonlinear adaptive control systems for reducing vibration transmission in applications, such as transportation systems include suspension systems. Magneto-rheological dampers use a novel class of smart fluid, whose apparent viscosity changes, as it is exposed to a magnetic field. The developed adaptive control scheme is designed to deal with the nonlinearities and uncertainties that commonly arise in most suspension applications. The present research is about numerical study evaluation of the controllers, on a seat suspension for heavy vehicles. The analytical evaluation indicates the effectiveness of the proposed adaptive control technique, in controlling vibration transmission, in the presence of both system nonlinearities and uncertainties. This work will provide a detailed account of the modeling, dynamic analysis, adaptive control development, and testing that will be performed throughout.
