Paper Abstract

Within this work a model of a 6 DOF (degree-of-freedom) vibration isolation system with semi-active control, using magnetorheological (MR) technology, is investigated. Parallel platform mechanisms are ideal candidates for 6 DOF positioning and vibration isolation. While active and passive vibration control have been extensively used in parallel platforms, a 6 DOF parallel platform which utilizes semi-active vibration control has not received as much attention. The advantages of semi-active control include reduced cost by using a simpler actuator intended for only positioning, reduced power requirements, and improved stability. Within this work, the legs of a parallel platform model are investigated by implementing a two DOF Simulink model. Each leg of the platform is modeled as a two DOF system with a magnetorheological (MR) damper for adjustable damping.
