Abstract
Elastomeric dampers are added to the rotor hub in order to mitigate air and ground resonances. While elastomeric dampers are a relatively simple solution they exhibit nonlinear hysteresis behavior. Characterization and modeling of the nonlinear elastomeric behavior is important to determine the effects of the damper on the rotor dynamics. The first goal of this research is to characterize the nonlinear behavior of a filled elastomeric double lap shear specimen under both single frequency and dual frequency sinusoidal loading. The second goal is to develop a nonlinear mechanisms-based analysis that captures both the hysteresis cycle behavior and linear characteristics. This analysis is done over a range of excitation amplitudes as would be seen by a damper in a helicopter environment.
