Abstract
The concept of vibration mitigation with smart fluids within flexible structures has attracted researcher's interest in the past two decades. A large amount of research work has been done on the structures with electro rheological fluids, but there has been a little work with the magneto rheological fluids. The objective of this research paper is to increase the mechanical vibration absorbing properties of the Magneto Rheological aircraft rib structure as a direct result of increasing its damping ratio via an increased stiffness. This is achieved through the implementation ofthe magnetic field upon the periphery of the proposed model structure under the influence of magnetic flux generated by 100 neodymium magnets, each of which generates a magnetic field intensity of 0.075 Tesla. Upon calculation of the damping ratio of all the entities involved, it was found that the in case of cross beam rib structure the damping ratio saw an increase of 44% and in case of vertical beam structure, the damping ratio saw an increase of 13.7%.
