Vibrations in structures can lead to a number of problems, not the least of which can be fatigue failures from excessive long term cyclic stresses. Passive techniques for vibration control, though sometimes limited in their capabilities, have been the primary method used in the past to attenuate vibrations. Recently active techniques have been developed to provide vibration control performance beyond...
Most precision positioning mechanisms and tracking systems contain instrument ball bearings that operate at ultra-low-speeds. Successful operation of these highly sensitive systems largely depends upon the ability to predict their bearing friction behavior. Until recently, very little research has been performed to understand the ultra-low-speed friction in coated bearings. Herein lies the scope of...
