“…Motion between two rough surfaces induces relatively high frequency signals/vibrations (see, for example, [11], [12], [13], [14], [15]). These signals are due to the deformation and rubbing of the two materials as contact is made and broken.…”

This paper presents a grasp force regulation strategy for precision grasps. The strategy makes no assumptions about object properties and surface characteristics and can be used with a wide range of grippers. It has two components: a slip signal detector that computes the magnitude of slip and a grasping force set point generator that acts on the detector's output. The force set point generator is designed to ensure that slip is eliminated without using excessive force. This is particularly important in several situations like grasping fragile objects or in-hand manipulation of thin small objects. Several experiments were conducted to simulate various grasping scenarios with different objects. Results show that the strategy was very successful in dealing with uncertainty in object mass, surface characteristics, or rigidity. The strategy is also insensitive to robot motion.

“…3 In a lubricated interface, the local dynamic responses can be complex and depend on molecular effects in the conEned lubricating Elms. 4 In engineering application, this vibration phenomenon is also called stick-slip and it is normal to most reciprocating motion. 5 When the sliding speed is low, these vibration phenomena can be observed easily.…”

This paper applies methods of theoretical analysis, lubrication calculation and test to study the vibration characteristics of marine rubber stern tube bearing (RSTB), and then the friction-induced vibration (FIV) phenomenon is investigated and the generation condition is analyzed. In order to study the tribological and vibration performance of the RSTB, a series of experiments are carried out, and then the stick-slip is the major precondition and the critical speed predominates within the motion. By increasing the specific pressure and the surface roughness of RSTB, it can lead to distinct vibration after the RSTB undergoes a transition from mild wear to severe wear. The analyses show how FIV generated and the results can be drawn as a function of effective measures to avoid abnormal vibration.

“…At the meantime friction-induced emissions in the lubricant film, confined between the mating surfaces, may occur which is referred to as viscous friction in this work. The friction response of such confined layers under shear stress can be complex and depends on the operating conditions, the nature of the surfaces and their mechanical and topographic characteristics, as well as the nature and shape of the confined fluid molecules [24][25][26][27]. These responses transmit energy from the flow to the surrounding solids as well as dissipating the kinetic energy of the flow as viscous shear stresses perform work.…”

Acoustic emission (AE) signals are useful for the condition monitoring of mechanical seals as tribological regimes affect the AE signatures. In this paper the investigation develops a mathematical model that can predict the energy of an AE signal under different tribological regimes. The developed model has been validated with experimental studies and satisfactory results have been perceived. Therefore, the model has strong potential to be used to obtain tribological behavior of mechanical seals and hence develop a reliable and accurate condition monitoring system under varying operating conditions.
