NONLINEAR DAMPING FOR VIBRATION ISOLATION AND CONTROL USING SEMI ACTIVE METHODS

This paper describes the semi active control of a single as well as two degree-of-freedom (sdof and 2dof) system with a magnetorheological (MR) damper. The investigation was done using a MATLAB/SIMULINK model. The objective of this paper is to present a comprehensive analysis of a SIMULINK model for a control strategy (using a Proportional-Integral Controller) to study the effect of a cubic viscous damping characteristic parameter on the transmissibility of sdof and 2dof vibration isolation systems. This research has substantial deductions for the analysis and design of viscously damped vibration isolators for a broad scope of engineering applications
