Application of Magnetorheological Dampers for Vehicle Seat Suspensions
… suspensions that employ magnetorheological (MR) dampers and skyhook control. An Isringhausen seat suspension that had been modified to replace the stock passive damper with a controllable MR damper was used to evaluate the problems and potential solutions. A seat suspension tester was built using …

Semi-Active Control of Air-Suspended Tuned Mass Dampers
… semi-active control of air-suspended tuned mass dampers with pendulum configuration was explored. A novel semi-active Air Sprung PTMD was designed, built, and evaluated, analytically and experimentally. The dynamics and control of such PTMD were evaluated, and its effectiveness was compared with …
