Numerical and Experimental Models of Dry Friction Damping in Aeroelastic Structures
Abstract
This project has represented an integrated modeling and experimental effort, with the following objectives: 1. Experimental characterization of the dynamics of both total and partial frictional slip; 2. Development of corresponding numerical strategies for treatment of such slip between elastically compliant structural members, exploring friction models and corresponding numerical strategies; and 3. Use of the results of 1) and 2) to investigate prediction of damping characteristics in idealized frictional damping connections. In meeting these objectives, fundamental advances have been made in friction modeling, connecting continuum mechanical models for friction with experimental measurements of friction damping at the microscale. An effective tool has been provided for accurate prediction of damping associated with dynamical turbine blade behavior.
