Book excerpt: Since many real systems are nonlinear, it is important to understand their characteristics for creating safe, efficient designs. This is true for structural dynamics, where the behavior of a system is influenced by joints, riveted connections, bolted connections, etc. These connections can be a source of sizeable damping for a structure. In addition, it is possible that these nonlinear connections will influence the system2s structural dynamic response. A better understanding of these nonlinear behaviors will be of great help for analytical models to account for such friction sources in the system dynamics of a structure. In order to complete this task, a sliding friction joint test rig was developed by another student, Mr. Robert Watts. Mr. Watts designed a rig that constrains two beams in contact. The test rig was designed in an attempt to isolate the beams and the friction joint. One beam can be transversely excited at various levels. The applied excitation levels and normal loads can be varied to investigate the joint from a full contact case to a partial slip case. With the rig, a number of experiments can be performed to investigate the contact of the beams. This paper evaluates the test rig to ensure it performs as designed. A modal test of the rig was performed and indeed verifies that the rig isolates the beams as a SDOF system over a frequency range of 40 to 300 Hz. The test setup details, such as testing software, hardware, loading, etc., are thoroughly documented to aid future research. Data was collected and analyzed to show that the current rig can be effectively operated under a full loading condition to a near slip condition. Characterization methods in both the frequency and time domain are given, with expected nonlinear trends shown in the data. Results such as FRF distortion and inverse FRF2s show a clear nonlinear damping. For time domain results, plots of hysteresis loops show a static coefficient of friction value near 0.60. Lastly, ways to improve specific areas such as beam alignment, guide rods, and normal loading are discussed with a new design.
