Abstract: The results of measurements showing large normal and frictional force oscillations during unlubricated smooth sliding between steel surfaces are presented. The measurements were made on a pin-on-disk ...

Abstract: Measurements of instantaneous normal and frictional forces have been made at smoothly sliding hemispherical steel contacts under nominally dry and boundary-lubricated conditions. Normalized contact ...

Abstract: The effects of normal contact vibrations, horizontal rider dynamics, and surface texture inputs are combined to examine dynamic loads at a contact during acceleration from rest to a steady state ...

Abstract: Measurements of instantaneous coefficients of friction and associated motions during start-up at a planar contact are presented for four different lubrication conditions. The various patterns of ...

Abstract: Nonlinear programming techniques are applied to obtain optimal tuning and damping parameters for dynamic absorbers. The optimization has been carried out for damped as well as undamped primary ...

Abstract: For more than twenty years, statistical energy analysis (SEA) has been used for the analysis of steady-state response distributions in complex coupled structures and sound-structure systems. ...

Abstract: The prediction, by the statistical energy analysis (SEA) method, of transient vibration envelopes for coupled systems is investigated. The relation between the time-varying energy transferred between ...

Abstract: Changes in friction due to angular motions at rough planar contacts are investigated using a compliant contact model that isolates an angular degree-of-freedom. Expressions are developed that ...

Abstract: Sets of unsteady friction experiments are presented. The data allow an interpretation to be made of the principal physical phenomena that occur during the transitions that take place during ...
