Paper Abstract

The main goal of this paper is to describe and understand the behavior of an absorption system with Coulomb damping with two degrees of freedom. In order to achieve this goal, a theoretical-computational model is developed and adjusted to the experimental results. The experimental model utilized consists of a cantilever beam with an absorption system installed on it. The absorption system is a spring-mass system with a friction element acting on its axis. The dynamic forces used in the experiments are: impacts, people jumping and harmonic excitation. A parametric study is performed with the adjusted theoretical-computational model, which indicates that the system is efficient, but some precautions should be considered in the project concept. These precautions are associated to nonlinear behavior of the response with this kind of damping. Finally, some relevant recommendations for the design of an absorption system are described.
