EXPERIMENTAL INVESTIGATION OF TANGENTIAL CONTACT STIFFNESS AND EQUIVALENT DAMPING
Journal Title: Proceedings in Manufacturing Systems - Year 2012, Vol 7, Issue 1
Abstract
In this paper, the phenomena of hysteretic behaviour of frictional contacts observed during reciprocating experiments are discussed. The hysteretic behaviour is determined theoretically based on the expression of hysteresis virgin curve. On the basis of the experimental analysis, an analytical method for determining the energy dissipation, equivalent damping and tangential contact stiffness is proposed. For all material contacts the same tendencies of the energy dissipation and equivalent damping can be observed which are increasing with load and displacement and, also for the contact stiffness which is increasing with increasing load and weakening with the displacement.
