An Analytical and Model Test Research Study on the Kaman Dynamic Antiresonant Vibration Isolator (Davi)

摘要

A parametric study was conducted on the basic unidirectional and two-dimensional DAVI Alpha to determine its isolation performance, and a general design criterion was obtained. Theoretical analyses, including damping across the series element, were done on the series-type DAVI's. A comparison was made of the series-type DAVI Beta and Gamma. Shock analyses for various types of inputs were done for the DAVI Alpha configuration. Experimental models of the unidirectional and two-dimensional DAVI Alpha and the series-type DAVI Beta and Gamma were constructed and tested to corroborate the theoretical results. Drop tests with three different inputs were done to determine the shock characteristics of the DAVI Alpha. (Author)
