The dynamic and steady-state response of flanged, bolted plates when excited with a hammer and acoustic methods exhibit nonlinear effects. Established Hilbert methods are used to estimate time-dependent and amplitude-dependent damping due to the joint, and the findings are presented here. Nonlinear damping of this system is sensitive to boundary conditions, and each of the first few modes behave nonlinearly in unique ways. Insight gained from knowledge about relationships between amplitude and damping may help to better understand friction joint dynamics. |
