Abstract:

This report contains results of analytical and experimental efforts related to dry friction damping. A general time history solution is developed for a multi-degree-of-freedom system which incorporates the use of nonlocal laws of friction. The formulation and the solution are entirely nonlinear and have the necessary flexibility for modelling specific engineering problems where the presence of friction at interfaces influences the dynamics. Two examples are chosen to illustrate certain important aspects of the procedures. A friction test assembly designed and fabricated under this program served as an experimental rig. The results from a limited number of tests are presented and discussed. A comparison between analytical and experimental results is given. Keywords Dry friction Vibrations and Structural dynamics.
