Abstract
The sensitivity of the response characteristics of a bolted interface to the bolt preload level used in the joint can often cause the dynamic properties of a system to be difficult to predict. A bolted interface test fixture was fabricated to investigate the effects of preload changes on the system dynamic response characteristics, and experimental results indicated that increases in bolt preload led to increases in modal frequency and decreases in modal damping. Furthermore, the system demonstrated a nonlinear behavior that resulted in the increase in modal frequency due to increases in impact amplitude when preload levels were low. The experimental results motivated the creation of a simplified low order nonlinear system model to represent the two dominant modes of the system. A model was used to describe the relationship between static stiffness and preload to account for the changes in initial bolt preload, and cubic stiffness terms were included to account for the amplitude dependent nonlinearity that was observed. The resulting model was able to accurately simulate system frequencies and general trends, but was unable to match some response characteristics of the system due to the lack of force information for the high amplitude loading used in the experiments.
