Magnetorheological landing gear: 2. Validation using experimental data [PDF]

, 2007
Aircraft landing gears are subjected to a wide range of excitation conditions with conflicting damping requirements. A novel solution to this problem is to implement semi-active damping using magnetorheological (MR) fluids. In part 1 of this contribution,
